Style

With React Native, you style your application using JavaScript. All of the core components accept a prop named style. The style names and values 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 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:

import React from 'react';
import { StyleSheet, Text, View } from 'react-native';
const LotsOfStyles = () => {
return (
<View style={styles.container}>
<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({
container: {
marginTop: 50,
},
bigBlue: {
color: 'blue',
fontWeight: 'bold',
fontSize: 30,
},
red: {
color: 'red',
},
});
export default 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 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.
