With React Native, you don't use a special language or syntax for defining styles. You just style your application using JavaScript. All of the core components accept a prop named `style`. The style names and [values](docs/colors.html) usually match how CSS works on the web, except names are written using camel casing, e.g `backgroundColor` rather than `background-color`.
|
|
|
|
The `style` prop can be a plain old JavaScript object. That's the simplest and what we usually use for example code. You can also pass an array of styles - the last style in the array has precedence, so you can use this to inherit styles.
|
|
|
|
As a component grows in complexity, it is often cleaner to use `StyleSheet.create` to define several styles in one place. Here's an example:
|
|
|
|
```ReactNativeWebPlayer
|
|
import React, { Component } from 'react';
|
|
import { AppRegistry, StyleSheet, Text, View } from 'react-native';
|
|
|
|
class LotsOfStyles extends Component {
|
|
render() {
|
|
return (
|
|
<View>
|
|
<Text style={styles.red}>just red</Text>
|
|
<Text style={styles.bigblue}>just bigblue</Text>
|
|
<Text style={[styles.bigblue, styles.red]}>bigblue, then red</Text>
|
|
<Text style={[styles.red, styles.bigblue]}>red, then bigblue</Text>
|
|
</View>
|
|
);
|
|
}
|
|
}
|
|
|
|
const styles = StyleSheet.create({
|
|
bigblue: {
|
|
color: 'blue',
|
|
fontWeight: 'bold',
|
|
fontSize: 30,
|
|
},
|
|
red: {
|
|
color: 'red',
|
|
},
|
|
});
|
|
|
|
AppRegistry.registerComponent('LotsOfStyles', () => LotsOfStyles);
|
|
```
|
|
|
|
One common pattern is to make your component accept a `style` prop which in
|
|
turn is used to style subcomponents. You can use this to make styles "cascade" the way they do in CSS.
|
|
|
|
There are a lot more ways to customize text style. Check out the [Text component reference](docs/text.html) for a complete list.
|
|
|
|
Now you can make your text beautiful. The next step in becoming a style master is to [learn how to control component size](docs/height-and-width.html).
