 ### Linking to a stylesheet {/*linking-to-a-stylesheet*/}
 
-If a component depends on a certain stylesheet in order to be displayed correctly, you can render a link to that stylesheet within the component. Your component will [suspend](http://localhost:3000/reference/react/Suspense) while the stylesheet is loading. You must supply the `precedence` prop, which tells React where to place this stylesheet relative to others — stylesheets with higher precedence can override those with lower precedence.

 <Note>
 When you want to use a stylesheet, it can be beneficial to call the [preinit](/reference/react-dom/preinit) function. Calling this function may allow the browser to start fetching the stylesheet earlier than if you just render a `<link>` component, for example by sending an [HTTP Early Hints response](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/103).

+React can move `<style>` components to the document's `<head>`, de-duplicate identical stylesheets, and [suspend](/reference/react/Suspense) while the stylesheet is loading.
 
 To opt into this behavior, provide the `href` and `precedence` props. React will de-duplicate styles if they have the same `href`. The precedence prop tells React where to rank the `<style>` DOM node relative to others in the document `<head>`, which determines which stylesheet can override the other.
