# Text

`Text` is component for displaying text. It supports style, basic touch
handling, and inherits typographic styles from ancestor elements.

The `Text` is unique relative to layout: child elements use text layout
(`inline`) rather than flexbox layout. This means that elements inside of a
`Text` are not rectangles, as they wrap when reaching the edge of their
container.

Unsupported React Native props:
`allowFontScaling` (ios),
`suppressHighlighting` (ios)

## Props

NOTE: `Text` will transfer all other props to the rendered HTML element.

(web) **accessibilityLabel**: string

Defines the text available to assistive technologies upon interaction with the
element. (This is implemented using `aria-label`.)

(web) **accessibilityRole**: oneOf(roles)

Allows assistive technologies to present and support interaction with the view
in a manner that is consistent with user expectations for similar views of that
type. For example, marking a touchable view with an `accessibilityRole` of
`button`. (This is implemented using [ARIA roles](http://www.w3.org/TR/wai-aria/roles#role_definitions)).

Note: Avoid changing `accessibilityRole` values over time or after user
actions. Generally, accessibility APIs do not provide a means of notifying
assistive technologies of a `role` value change.

(web) **accessible**: bool = true

When `false`, the text is hidden from assistive technologies. (This is
implemented using `aria-hidden`.)

**children**: any

Child content.

**numberOfLines**: number

Truncates the text with an ellipsis after this many lines. Currently only supports `1`.

**onPress**: function

This function is called on press.

**style**: style

+ ...[View#style](View.md)
+ `color`
+ `fontFamily`
+ `fontSize`
+ `fontStyle`
+ `fontWeight`
+ `letterSpacing`
+ `lineHeight`
+ `textAlign`
+ `textAlignVertical`
+ `textDecorationLine`
+ `textShadow`
+ `textTransform`
+ `whiteSpace`
+ `wordWrap`
+ `writingDirection`

**testID**: string

Used to locate this view in end-to-end tests.

## Examples

```js
import React, { Component, PropTypes, StyleSheet, Text } from 'react-native'

export default class PrettyText extends Component {
  static propTypes = {
    ...Text.propTypes,
    color: PropTypes.oneOf(['white', 'gray', 'red']),
    size: PropTypes.oneOf(['small', 'normal', 'large']),
    weight: PropTypes.oneOf(['light', 'normal', 'bold'])
  };

  static defaultProps = {
    ...Text.defaultProps,
    color: 'gray',
    size: 'normal',
    weight: 'normal'
  };

  render() {
    const { color, size, style, weight, ...other } = this.props;

    return (
      <Text
        ...other
        style={[
          style,
          colorStyles[color],
          sizeStyles[size],
          weightStyles[weight]
        ]}
      />
    );
  }
}

const colorStyles = StyleSheet.create({
  white: { color: 'white' },
  gray: { color: 'gray' },
  red: { color: 'red' }
})

const sizeStyles = StyleSheet.create({
  small: { fontSize: '0.85rem', padding: '0.5rem' },
  normal: { fontSize: '1rem', padding: '0.75rem' },
  large: { fontSize: '1.5rem', padding: '1rem' }
})

const weightStyles = StyleSheet.create({
  light: { fontWeight: '300' },
  normal: { fontWeight: '400' },
  bold: { fontWeight: '700' }
})
