-# Contributing to this project
+# Contributing
 
-The issue tracker is the preferred channel for [bug reports](#bugs),
-[features requests](#features) and [submitting pull
-requests](#pull-requests).
+We are open to, and grateful for, any contributions made by the community.

-## Bug reports
+## Reporting Issues and Asking Questions
 
-A bug is a _demonstrable problem_ that is caused by the code in the repository.
-Good bug reports are extremely helpful - thank you!
+Before opening an issue, please search the [issue
+tracker](https://github.com/necolas/react-native-web/issues) to make sure your
+issue hasn't already been reported.
 
-Guidelines for bug reports:
+## Development
 
-1. **Use the GitHub issue search** &mdash; check if the issue has already been
-   reported.
+Visit the [Issue tracker](https://github.com/necolas/react-native-web/issues)
+to find a list of open issues that need attention.
 
-2. **Check if the issue has been fixed** &mdash; try to reproduce it using the
-   latest `master` or development branch in the repository.
+Fork, then clone the repo:
 
-3. **Isolate the problem** &mdash; create a [reduced test
-   case](http://css-tricks.com/reduced-test-cases/) and a live example.
+```
+git clone https://github.com/your-username/react-native-web.git
+```
 
-A good bug report contains as much detail as possible. What is your
-environment? What steps will reproduce the issue? What browser(s) and OS
-experience the problem? What would you expect to be the outcome? All these
-details really help!
+Run the examples:
 
-Example:
+```
+npm run examples
+```
 
-> Short and descriptive example bug report title
->
-> A summary of the issue and the browser/OS environment in which it occurs. If
-> suitable, include the steps required to reproduce the bug.
->
-> 1. This is the first step
-> 2. This is the second step
-> 3. Further steps, etc.
->
-> `<url>` - a link to the reduced test case
->
-> Any other information you want to share that is relevant to the issue being
-> reported. This might include the lines of code that you have identified as
-> causing the bug, and potential solutions (and your opinions on their
-> merits).
+### Building
 
+```
+npm run build
+```
 
-<a name="features"></a>
-## Feature requests
+To create a UMD build:
 
-Feature requests are welcome. But take a moment to find out whether your idea
-fits with the scope and aims of the project. It's up to *you* to make a strong
-case to convince the project's developers of the merits of this feature. Please
-provide as much detail and context as possible.
+```
+npm run build:umd
+```
 
+### Testing and Linting
 
-<a name="pull-requests"></a>
-## Pull requests
+To run the tests:
 
-Good pull requests - patches, improvements, new features - are a fantastic
-help. Please keep them focused in scope and avoid containing unrelated commits.
+```
+npm run test
+```
 
-**Please ask first** before embarking on any significant pull request (e.g.
-implementing new features or components, refactoring code), otherwise you risk
-spending a lot of time working on something that the project's developers might
-not want to merge into the project.
+To continuously watch and run tests, run the following:
 
-Development commands:
+```
+npm run test:watch
+```
 
-* `npm start` – start the dev server and develop against live examples
-* `npm run lint` – run the linter
-* `npm run specs` – run the unit tests
-* `npm run build` – generate a build
+To perform linting, run the following:
 
-Please follow this process for submitting a patch:
+```
+npm run lint
+```
 
-1. [Fork](http://help.github.com/fork-a-repo/) the project, clone your fork,
-   and configure the remotes:
+### New Features
 
-   ```bash
-   # Clone your fork of the repo into the current directory
-   git clone https://github.com/<your-username>/react-native-web
-   # Navigate to the newly cloned directory
-   cd react-native-web
-   # Assign the original repo to a remote called "upstream"
-   git remote add upstream https://github.com/necolas/react-native-web
-   ```
+Please open an issue with a proposal for a new feature or refactoring before
+starting on the work. We don't want you to waste your efforts on a pull request
+that we won't want to accept.
 
-2. If you cloned a while ago, get the latest changes from upstream:
+## Submitting Changes
 
-   ```bash
-   git checkout master
-   git pull upstream master
-   ```
+* Open a new issue in the [Issue tracker](https://github.com/necolas/react-native-web/issues).
+* Fork the repo.
+* Create a new feature branch based off the `master` branch.
+* Make sure all tests pass and there are no linting errors.
+* Submit a pull request, referencing any issues it addresses.
 
-3. Create a new topic branch (off the main project development branch) to
-   contain your feature, change, or fix:
+Please try to keep your pull request focused in scope and avoid including unrelated commits.
 
-   ```bash
-   git checkout -b <topic-branch-name>
-   ```
+After you have submitted your pull request, we'll try to get back to you as soon as possible. We may suggest some changes or improvements.
 
-4. Commit your changes in logical chunks. Please adhere to these [git commit
-   message guidelines](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
-   or your code is unlikely be merged into the main project. Use Git's
-   [interactive rebase](https://help.github.com/articles/interactive-rebase)
-   feature to tidy up your commits before making them public.
-
-5. Locally merge (or rebase) the upstream development branch into your topic branch:
-
-   ```bash
-   git pull [--rebase] upstream master
-   ```
-
-6. Push your topic branch up to your fork:
-
-   ```bash
-   git push origin <topic-branch-name>
-   ```
-
-7. [Open a Pull Request](https://help.github.com/articles/using-pull-requests/)
-    with a clear title and description.
-
-**IMPORTANT**: By submitting a patch, you agree to allow the project owner to
-license your work under the same license as that used by the project.
+Thank you for contributing!

-## Use

-React Native for Web exports its components and a reference to the `React`
-installation. Styles are authored in JavaScript as plain objects.
+Browser support: Chrome, Firefox, Safari >= 7, IE 10, Edge.
+
+## Overview
+
+This is a web implementation of React Native components and APIs. The React
+Native components are good web application building blocks, and provide a common
+foundation for component libraries.
+
+For example, the [`View`](docs/apis/View.md) component makes it easy to build
+common layouts with flexbox, such as stacked and nested boxes with margin and
+padding. And the [`StyleSheet`](docs/guides/style.md) API converts styles
+defined in JavaScript to "atomic" CSS.
+
+## Example
+
+More examples can be found in the [`examples` directory](examples).
 
 ```js
-import React, { View } from 'react-native-web'
+import React, { AppRegistry, Image, StyleSheet, Text, View } from 'react-native'
 
-class MyComponent extends React.Component {
-  render() {
-    return (
-      <View style={styles.root} />
-    )
-  }
-}
+// Components
+const Card = ({ children }) => <View style={styles.card}>{children}</View>
+const Title = ({ children }) => <Text style={styles.title}>{children}</Text>
+const Photo = ({ uri }) => <Image source={{ uri }} style={styles.image} />
+const App = () => (
+  <Card>
+    <Title>App Card</Title>
+    <Photo uri="/some-photo.jpg" />
+  </Card>
+)
 
-const styles = {
-  root: {
-    borderColor: 'currentcolor'
-    borderWidth: '5px',
-    flexDirection: 'row'
-    height: '5em'
-  }
-}
-```
+// App registration and rendering
+AppRegistry.registerComponent('MyApp', () => App)
+AppRegistry.runApplication('MyApp', { rootTag: document.getElementById('react-root') })
 
-## Components
-
-Partial implementations of…
-
-* [`Image`](docs/components/Image.md)
-* [`Text`](docs/components/Text.md)
-* [`TextInput`](docs/components/TextInput.md)
-* [`View`](docs/components/View.md)
-
-## Styling
-
-React Native Web provides a mechanism to declare all your styles and layout
-inline with the components that use them. The `View` component makes it easy
-to build common layouts with flexbox, such as stacked and nested boxes with
-margin and padding.
-
-Styling is identical to using inline styles in React, but most inline styles
-are converted to single-purpose classes. The current implementation includes
-300+ precomputed CSS declarations (~4.5KB gzipped) that cover a large
-proportion of common styles. A more sophisticated build-time implementation may
-produce a slightly larger CSS file for large apps, and fall back to fewer
-inline styles.  Read more about the [styling
-strategy](docs/react-native-web-style/styling.md).
-
-See this [guide to flexbox][flexbox-guide-url].
-
-```js
-import React, { Image, Text, View } from 'react-native-web'
-
-class App extends React.Component {
-  render() {
-    return (
-      <View style={styles.row}>
-        <Image
-          source={{ uri: 'http://facebook.github.io/react/img/logo_og.png' }}
-          style={styles.image}
-        />
-        <View style={styles.text}>
-          <Text style={styles.title}>
-            React Native Web
-          </Text>
-          <Text style={styles.subtitle}>
-            Build high quality web apps using React
-          </Text>
-        </View>
-      </View>
-    )
-  },
-})
-
-const styles = {
-  row: {
-    flexDirection: 'row',
-    margin: 40
-  },
-  image: {
-    height: 40,
-    marginRight: 10,
-    width: 40,
-  },
-  text: {
-    flex: 1,
+// Styles
+const styles = StyleSheet.create({
+  card: {
+    flexGrow: 1,
     justifyContent: 'center'
   },

-`View` is a flexbox container and the fundamental building block for UI. It is
-designed to be nested inside other `View`'s and to have 0-to-many children of
-any type.
-
-## PropTypes
-
-All other props are transferred directly to the `element`.
-
-+ `component`: `func` or `string` (default `"div"`)
-+ `pointerEvents`: `oneOf('all', 'box-only', 'box-none', 'none')`
-+ `style`: `ViewStylePropTypes`
-
-## ViewStylePropTypes
-
-+ BackgroundPropTypes
-+ BorderThemePropTypes
-+ LayoutPropTypes
-+ `boxShadow`: `string`
-+ `color`: `string`
-+ `opacity`: `number`
-
-## ViewStyleDefaultProps
-
-Implements the default styles from
-[facebook/css-layout](https://github.com/facebook/css-layout).
-
-1. All the flex elements are oriented from top-to-bottom, left-to-right and do
-   not shrink. This is how things are laid out using the default CSS settings
-   and what you'd expect.
-
-2. The most convenient way to express the relation between width and other
-   box-model properties.
-
-3. Everything is `display:flex` by default. All the behaviors of `block` and
-   `inline-block` can be expressed in term of flex but not the opposite.
-
-4. Everything is `position:relative`. This makes `position:absolute` target the
-   direct parent and not some parent which is either relative or absolute. If
-   you want to position an element relative to something else, you should move
-   it in the DOM instead of relying of CSS. It also makes `top`, `left`,
-   `right`, `bottom` do something when not specifying `position:absolute`.
-
-```js
-const ViewDefaultStyle = {
-  alignItems: 'stretch', // 1
-  borderWidth: 0,
-  borderStyle: 'solid',
-  boxSizing: 'border-box', // 2
-  display: 'flex', // 3
-  flexBasis: 'auto', // 1

-  flexShrink: 0, // 1

+# AppRegistry
+
+`AppRegistry` is the control point for registering, running, prerendering, and
+unmounting all apps. App root components should register themselves with
+`AppRegistry.registerComponent`. Apps can be run by invoking
+`AppRegistry.runApplication`, and prerendered by invoking
+`AppRegistry.prerenderApplication` (see the [client and server rendering
+guide](../guides/rendering.md) for more details).
+
+To "stop" an application when a view should be destroyed, call
+`AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was passed
+into `runApplication`. These should always be used as a pair.
+
+## Methods
+
+(web) static **prerenderApplication**(appKey:string, appParameters: object)
+
+Renders the given application to an HTML string. Use this for server-side
+rendering. Return object is of type `{ html: string; style: string; }`, where
+`html` the prerendered HTML, and `style` is the prerendered style sheet.
+
+static **registerConfig**(config: Array<AppConfig>)
+
+Registry multiple applications. `AppConfig` is of type `{ appKey: string;
+component: ComponentProvider; run?: Function }`.
+
+static **registerComponent**(appKey: string, getComponentFunc: ComponentProvider)
+
+Register a component provider under the given `appKey`.
+
+static **registerRunnable**(appKey: string, run: Function)
+
+Register a custom render function for an application. The function will receive
+the `appParameters` passed to `runApplication`.
+
+static **getAppKeys**()
+
+Returns all registered app keys.
+
+static **runApplication**(appKey: string, appParameters?: object)
+
+Runs the application that was registered under `appKey`. The `appParameters`
+must include the `rootTag` into which the application is rendered, and
+optionally any `initialProps`.
+
+static **unmountApplicationComponentAtRootTag**(rootTag: HTMLElement)
+
+To "stop" an application when a view should be destroyed, call

+providing the `handler`. The handler is called with the app state value.
+
+static **removeEventListener**(type: string, handler: Function)
+
+Remove a handler by passing the change event `type` and the `handler`.
+
+## Examples
+
+To see the current state, you can check `AppState.currentState`, which will be
+kept up-to-date. This example will only ever appear to say "Current state is:
+active" because the app is only visible to the user when in the `active` state,
+and the null state will happen only momentarily.

+# AsyncStorage
+
+`AsyncStorage` is a simple, asynchronous, persistent, key-value storage system
+that is global to the domain. It's a facade over, and should be used instead of
+`window.localStorage` to provide an asynchronous API and multi functions. Each
+method returns a `Promise` object.
+
+It is recommended that you use an abstraction on top of `AsyncStorage` instead
+of `AsyncStorage` directly for anything more than light usage since it operates
+globally.
+
+The batched functions are useful for executing a lot of operations at once,
+allowing for optimizations to provide the convenience of a single promise after
+all operations are complete.
+
+## Methods
+
+static **clear**()
+
+Erases all AsyncStorage. You probably don't want to call this - use
+`removeItem` or `multiRemove` to clear only your own keys instead. Returns a

+
+static **getItem**(key: string)
+
+Fetches the value of the given key. Returns a Promise object.
+
+static **mergeItem**(key: string, value: string)
+
+Merges existing value with input value, assuming they are stringified JSON.
+Returns a Promise object.
+
+static **multiGet**(keys: Array<string>)
+
+`multiGet` results in an array of key-value pair arrays that matches the input
+format of `multiSet`. Returns a Promise object.
+
+```js
+multiGet(['k1', 'k2']) -> [['k1', 'val1'], ['k2', 'val2']]
+```
+
+static **multiMerge**(keyValuePairs: Array<Array<string>>)
+
+multiMerge takes an array of key-value array pairs that match the output of
+`multiGet`. It merges existing values with input values, assuming they are
+stringified JSON. Returns a Promise object.
+
+static **multiRemove**(keys: Array<string>)
+
+Delete all the keys in the keys array. Returns a Promise object.
+
+static **multiSet**(keyValuePairs: Array<Array<string>>)
+
+`multiSet` takes an array of key-value array pairs that match the output of
+`multiGet`. Returns a Promise object.
+
+```js
+multiSet([['k1', 'val1'], ['k2', 'val2']]);
+```
+
+static **removeItem**(key: string)

+# NativeMethods
+
+React Native for Web provides several methods to directly access the underlying
+DOM node. This can be useful in cases when you want to focus a view or measure
+its on-screen dimensions, for example.
+
+The methods described are available on most of the default components provided
+by React Native for Web. Note, however, that they are *not* available on the
+composite components that you define in your own app. For more information, see
+[Direct Manipulation](../guides/direct-manipulation.md).
+
+## Methods
+
+**blur**()
+
+Removes focus from an input or view. This is the opposite of `focus()`.
+
+**focus**()
+
+Requests focus for the given input or view. The exact behavior triggered will
+depend the type of view.
+
+**measure**(callback: (x, y, width, height, pageX, pageY) => void)
+
+For a given view, `measure` determines the offset relative to the parent view,
+width, height, and the offset relative to the viewport. Returns the values via
+an async callback.
+
+Note that these measurements are not available until after the rendering has
+been completed.
+
+**measureLayout**(relativeToNativeNode: DOMNode, onSuccess: (x, y, width, height) => void)
+
+Like `measure`, but measures the view relative to another view, specified as
+`relativeToNativeNode`. This means that the returned `x`, `y` are relative to
+the origin `x`, `y` of the ancestor view.
+
+**setNativeProps**(nativeProps: Object)
+
+This function sends props straight to the underlying DOM node. See the [direct
+manipulation](../guides/direct-manipulation.md) guide for cases where
+`setNativeProps` should be used.

+static **roundToNearestPixel**(layoutSize: number)
+
+Rounds a layout size (dp) to the nearest layout size that corresponds to an

+the view directly (discouraged) or by bounding the height of ancestor views.
+
+## Props
+
+**children**: any
+
+Child content.
+
+**contentContainerStyle**: style
+
+These styles will be applied to the scroll view content container which wraps
+all of the child views.
+
+**horizontal**: bool = false
+
+When true, the scroll view's children are arranged horizontally in a row
+instead of vertically in a column.
+
+**onScroll**: function
+
+Fires at most once per frame during scrolling. The frequency of the events can
+be contolled using the `scrollEventThrottle` prop.
+
+**scrollEnabled**: bool = true
+
+When false, the content does not scroll.
+
+**scrollEventThrottle**: number = 0
+
+This controls how often the scroll event will be fired while scrolling (in
+events per seconds). A higher number yields better accuracy for code that is
+tracking the scroll position, but can lead to scroll performance problems. The
+default value is `0`, which means the scroll event will be sent only once each
+time the view is scrolled.

+# Accessibility
+
+On the Web, assistive technologies derive useful information about the
+structure, purpose, and interactivity of apps from their [HTML
+elements][html-accessibility-url], attributes, and [ARIA in
+HTML][aria-in-html-url].
+
+The most common and best supported accessibility features of the Web are
+exposed as the props: `accessible`, `accessibilityLabel`,
+`accessibilityLiveRegion`, and `accessibilityRole`.
+
+React Native for Web does not provide a way to directly control the type of the
+rendered HTML element. The `accessibilityRole` prop is used to infer an
+[analogous HTML element][html-aria-url] to use in addition to the resulting
+ARIA `role`, where possible. While this may contradict some ARIA
+recommendations, it also helps avoid certain HTML5 conformance errors and
+accessibility anti-patterns (e.g., giving a `heading` role to a `button`
+element).
+
+For example:

+# Direct manipulation
+
+It is sometimes necessary to make changes directly to a component without using
+state/props to trigger a re-render of the entire subtree – in the browser, this
+is done by directly modifying a DOM node. `setNativeProps` is the React Native
+equivalent to setting properties directly on a DOM node. Use direct
+manipulation when frequent re-rendering creates a performance bottleneck Direct
+manipulation will not be a tool that you reach for frequently.
+
+## `setNativeProps` and `shouldComponentUpdate`
+
+`setNativeProps` is imperative and stores state in the native layer (DOM,
+UIView, etc.) and not within your React components, which makes your code more
+difficult to reason about. Before you use it, try to solve your problem with
+`setState` and `shouldComponentUpdate`.
+
+## Avoiding conflicts with the render function
+
+If you update a property that is also managed by the render function, you might
+end up with some unpredictable and confusing bugs because anytime the component
+re-renders and that property changes, whatever value was previously set from
+`setNativeProps` will be completely ignored and overridden.
+
+## Why use `setNativeProps` on Web?
+
+Using `setNativeProps` in web-specific code is required when making changes to
+`className` or `style`, as these properties are controlled by React Native for
+Web and setting them directly may cause unintended rendering issues.
+
+```js
+setOpacityTo(value) {
+  this._childElement.setNativeProps({
+    style: { opacity: value }
+  })
+}
+```
+
+## Composite components and `setNativeProps`
+
+Composite components are not backed by a DOM node, so you cannot call
+`setNativeProps` on them. Consider this example:
+
+```js
+const MyButton = (props) => (
+  <View>
+    <Text>{props.label}</Text>
+  </View>
+)
+
+const App = () => (
+  <TouchableOpacity>
+    <MyButton label="Press me!" />
+  </TouchableOpacity>
+)
+```
+
+If you run this you will immediately see this error: `Touchable` child must
+either be native or forward `setNativeProps` to a native component. This occurs
+because `MyButton` isn't directly backed by a native view whose opacity should
+be set. You can think about it like this: if you define a component with
+`React.Component/createClass` you would not expect to be able to set a style
+prop on it and have that work - you would need to pass the style prop down to a
+child, unless you are wrapping a native component. Similarly, we are going to
+forward `setNativeProps` to a native-backed child component.
+
+## Forward `setNativeProps` to a child
+
+All we need to do is provide a `setNativeProps` method on our component that
+calls `setNativeProps` on the appropriate child with the given arguments.
+
+```js
+class MyButton extends React.Component {
+  setNativeProps(nativeProps) {
+    this._root.setNativeProps(nativeProps)
+  }
+
+  render() {
+    return (
+      <View ref={component => this._root = component}>
+        <Text>{this.props.label}</Text>
+      </View>
+    )
+  }
+}
+```
+
+You can now use `MyButton` inside of `TouchableOpacity`!
+
+## `setNativeProps` to clear `TextInput` value
+
+Another very common use case of `setNativeProps` is to clear the value of a
+`TextInput`. For example, the following code demonstrates clearing the input
+when you tap a button:
+
+```js
+class App extends React.Component {
+  _handlePress() {
+    this._textInput.setNativeProps({ text: '' })
+  }
+
+  render() {
+    return (
+      <View style={styles.container}>
+        <TextInput
+          ref={component => this._textInput = component}
+          style={styles.textInput}
+        />
+        <TouchableOpacity onPress={this._handlePress.bind(this)}>
+          <Text>Clear text</Text>
+        </TouchableOpacity>
+      </View>
+    )
+  }
+}
+```

+# Known issues
+
+## Missing modules and Views
+
+This is an initial release of React Native for Web, therefore, not all of the
+views present on iOS/Android are released on Web. We are very much interested in
+the community's feedback on the next set of modules and views.
+
+Not all the modules or views for iOS/Android can be implemented on Web. In some
+cases it will be necessary to use a Web counterpart.
+
+## Missing component props
+
+There are properties that do not work across all platforms. All web-specific
+props are annotated with `(web)` in the documentaiton.
+
+## Platform parity
+
+There are some known issues in React Native where APIs could be made more
+consistent between platforms. For example, React Native for Web includes
+`ActivityIndicator` and a horizontal `ProgressBar`.
+
+Other parts of React Native, such as the `Animated` and `PanResponder` APIs,
+are highly complex and have not yet been ported to React Native for Web. Given
+the difficulties keeping these APIs in sync with React Native, we'd prefer the
+APIs to be published as separate npm packages. If not, we will consider a web
+implementation, possibly using the [Web Animations
+API/polyfill](https://github.com/web-animations/web-animations-js)

+Web-specific implementations can use the `*.web.js` naming pattern, which
+webpack will resolve.
+
+Minor platform differences can use the `Platform` module.

+# Style
+
+React Native for Web relies on JavaScript to define styles for your
+application. Along with a novel JS-to-CSS conversion strategy, this allows you
+to avoid issues arising from the [7 deadly sins of
+CSS](https://speakerdeck.com/vjeux/react-css-in-js):
+
+1. Global namespace
+2. Dependency hell
+3. No dead code elimination
+4. No code minification
+5. No sharing of constants
+6. Non-deterministic resolution
+7. Lack of isolation
+
+## Defining styles
+
+Styles should be defined outside of the component:
+
+```js
+class Example extends React.Component {}
+
+const styles = StyleSheet.create({
+  heading: {
+    color: 'gray',
+    fontSize: '2rem'
+  },
+  text: {
+    color: 'gray',
+    fontSize: '1.25rem'
+  }
+})
+```
+
+Using `StyleSheet.create` is optional but provides some key advantages: styles
+are immutable in development, styles are converted to CSS rather than applied
+as inline styles, and styles are only created once for the application and not
+on every render.
+
+The attribute names and values are a subset of CSS. See the `style`
+documentation of individual components.
+
+## Using styles
+
+All the React Native components accept a `style` attribute.
+
+```js
+<Text style={styles.text} />
+<View style={styles.view} />
+```
+
+A common pattern is to conditionally add style based on a condition:
+
+```js
+// either
+<View style={[
+  styles.base,
+  this.state.active && styles.active
+]} />
+
+// or
+<View style={{
+  ...styles.base,
+  ...(this.state.active && styles.active)
+}} />
+```
+
+## Composing styles
+
+In order to let a call site customize the style of your component children, you
+can pass styles around. Use `View.propTypes.style` and `Text.propTypes.style` in
+order to make sure only valid styles are being passed.
+
+```js
+class List extends React.Component {
+  static propTypes = {
+    style: View.propTypes.style,
+    elementStyle: View.propTypes.style,
+  }
+
+  render() {
+    return (
+      <View style={this.props.style}>
+        {elements.map((element) =>
+          <View style={[ styles.element, this.props.elementStyle ]} />
+        )}
+      </View>
+    );
+  }
+}
+```
+
+In another file:
+
+```js
+<List style={styles.list} elementStyle={styles.listElement} />
+```
+
+You also have much greater control over how styles are composed when compared
+to using class names. For example, you may choose to accept a limited subset
+of style props in the component's API, and control when they are applied:
+
+```js
+class List extends React.Component {
+  static propTypes = {
+    children: React.PropTypes.any,
+    // limit which styles are accepted
+    style: React.PropTypes.shape({
+      borderColor: View.propTypes.borderColor,
+      borderWidth: View.propTypes.borderWidth
+    })
+  }
+
+  render() {
+    return (
+      <View
+        children={children}
+        style={[
+          this.props.style,
+          // override border-color when scrolling
+          isScrolling && { borderColor: 'transparent' }
+        ]}
+      />
+    )
+  }
+}
+```
+
+## Media Queries
+
+`StyleSheet.create` is a way of defining the styles your application requires;
+it does not concern itself with _where_ or _when_ those styles are applied to
+elements.
+
+There are various React libraries wrapping JavaScript Media Query API's, e.g.,
+[react-media-queries](https://github.com/bloodyowl/react-media-queries),
+[media-query-fascade](https://github.com/tanem/media-query-facade), or
+[react-responsive](https://github.com/contra/react-responsive). This has the
+benefit of co-locating breakpoint-specific DOM and style changes.
+
+## Pseudo-classes and pseudo-elements
+
+Pseudo-classes like `:hover` and `:focus` can be implemented with the events
+(e.g. `onFocus`). Pseudo-elements are not supported; elements should be used
+instead.
+
+## How it works
+
+Every call to `StyleSheet.create` extracts the unique _declarations_ and
+converts them to a unique CSS rule. This is sometimes referred to as "atomic
+CSS". All the core components map their `style` property-value pairs to the
+corresponding `className`'s.
+
+By doing this, the total size of the generated CSS is determined by the
+total number of unique declarations (rather than the total number of rules in
+the application), making it viable to inline the style sheet when pre-rendering
+on the server. Styles are updated if new module bundle are loaded asynchronously.
+
+JavaScript definition:
+
+```js
+const styles = StyleSheet.create({
+  heading: {
+    color: 'gray',
+    fontSize: '2rem'
+  },
+  text: {
+    color: 'gray',
+    fontSize: '1.25rem'
+  }
+})
+```
+
+CSS output:
+
+```css
+._s1 { color: gray; }
+._s2 { font-size: 2rem; }
+._s3 { font-size: 1.25rem; }
+```
+
+Rendered HTML:
+
+```html
+<span className="_s1 _s2">Heading</span>
+<span className="_s1 _s3">Text</span>
+```
+
+### Reset
+
+You **do not** need to include a CSS reset or
+[normalize.css](https://necolas.github.io/normalize.css/).
+
+React Native for Web includes a very small CSS reset taken from normalize.css.
+It removes unwanted User Agent styles from (pseudo-)elements beyond the reach
+of React (e.g., `html`, `body`) or inline styles (e.g., `::-moz-focus-inner`).
+
+```css
+html {
+  font-family: sans-serif;
+  -ms-text-size-adjust: 100%;
+  -webkit-text-size-adjust: 100%;
+}
+
+body {
+  margin: 0;
+}
+
+button::-moz-focus-inner,
+input::-moz-focus-inner {
+  border: 0;
+  padding: 0;
+}
+
+input[type="search"]::-webkit-search-cancel-button,
+input[type="search"]::-webkit-search-decoration {
+  -webkit-appearance: none;
+}
+
+ol,
+ul,
+li {
+  list-style:none
+}
+```

-# Styling strategy
-
-Using the `style` attribute would normally produce inline styles. There are
-several existing approaches to using the `style` attribute, some of which
-convert inline styles to static CSS:
-[jsxstyle](https://github.com/petehunt/jsxstyle),
-[react-free-style](https://github.com/blakeembrey/react-free-style/),
-[react-inline](https://github.com/martinandert/react-inline),
-[react-native](https://facebook.github.io/react-native/),
-[react-style](https://github.com/js-next/react-style),
-[stilr](https://github.com/kodyl/stilr).
-
-## Style syntax: native vs proprietary data structure
-
-React Web SDK (in a divergence from React Native) represents style using plain
-JS objects:
-
-```js
-<Text style={styles.root}>...</Text>
-
-const styles = {
-  root: {
-    background: 'transparent',
-    display: 'flex',
-    flexGrow: 1,
-    justifyContent: 'center'
-  }
-};
-```
-
-Most approaches to managing style in React introduce a proprietary data
-structure, often via an implementation of `Stylesheet.create`.
-
-```js
-<Text style={styles.root}>...</Text>
-
-const styles = Stylesheet.create({
-  root: {
-    background: 'transparent',
-    display: 'flex',
-    flexGrow: 1,
-    justifyContent: 'center'
-  }
-});
-```
-
-## JS-to-CSS: conversion strategies
-
-One strategy for converting styles from JS to CSS is to map style objects to
-CSS rules. Another strategy is to map declarations to declarataions.
-
-![](../static/styling-strategy.png)
-
-Mapping entire `style` objects to CSS rules can lead to increasingly large CSS
-files. Each new component adds new rules to the stylesheet.
-
-React Web SDK includes a proof-of-concept for the strategy of automatically
-mapping unique declarations to declarations, via a unique selector for each
-declaration. This strategy results in smaller CSS files because an application
-has fewer unique declarations than total declarations. Creating a new
-component with no new unique declarations results in no change to the CSS file.
-
-For example:
-
-```js
-<Text style={styles.root}>...</Text>
-
-const styles = {
-  root: {
-    background: 'transparent',
-    display: 'flex',
-    flexGrow: 1,
-    justifyContent: 'center'
-  }
-};
-```
-
-Yields:
-
-```html
-<span className="_abcde _fghij _klmno _pqrst">...</span>
-```
-
-And is backed by:
-
-```css
-._abcde { background: transparent }
-._fghij { display: flex }
-._klmno { flex-grow: 1 }
-._pqrst { justify-content: center }
-```
-
-The current implementation uses a precomputed CSS library of single-declaration
-rules, with obfuscated selectors. This handles a signficant portion of possible
-declarations. But a build-time implementation would produce more accurate CSS
-files and fall through to inline styles significantly less often.
-
-
-(CSS libraries like [Atomic CSS](http://acss.io/),
-[Basscss](http://www.basscss.com/), [SUIT CSS](https://suitcss.github.io/), and
-[tachyons](http://tachyons.io/) are attempts to limit style scope and limit
-stylesheet growth in a similar way. But they're CSS utility libraries, each with a
-particular set of classes and features to learn. All of them require developers
-to manually connect CSS classes for given styles.)
-
-## Dynamic styles: use inline styles
-
-Some styles cannot be resolved ahead of time and continue to rely on inline
-styles:
-
-```js
-<View style={{ backgroundColor: (Math.random() > 0.5 ? 'red' : 'black') }}>...</Text>
-```
-
-## Media Queries, pseudo-classes, and pseudo-elements
-
-Media Queries could be replaced with `mediaMatch`. This would have the added
-benefit of co-locating breakpoint-specific DOM and style changes. Perhaps Media
-Query data could be accessed on `this.content`?
-
-Pseudo-classes like `:hover` and `:focus` can be handled with JavaScript.
-
-Pseudo-elements should be avoided in general, but for particular cases like
-`::placeholder` it might be necessary to reimplement it in the SDK's
-`TextInput` component (see React Native's API).
