You just style your application using JavaScript. All of the core components accept a prop named <code>style</code>. The style names and <a href="/react-native/docs/colors">values</a> usually match how CSS works on the web, except names are written using camel casing, e.g <code>backgroundColor</code> rather than <code>background-color</code>.</p>
<p>The <code>style</code> 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.</p>
<p>As a component grows in complexity, it is often cleaner to use <code>StyleSheet.create</code> to define several styles in one place. Here's an example:</p>

<p>One common pattern is to make your component accept a <code>style</code> prop which in turn is used to style subcomponents. You can use this to make styles &quot;cascade&quot; the way they do in CSS.</p>
<p>There are a lot more ways to customize text style. Check out the <a href="/react-native/docs/text">Text component reference</a> for a complete list.</p>
<p>Now you can make your text beautiful. The next step in becoming a style master is to <a href="/react-native/docs/height-and-width">learn how to control component size</a>.</p>
