Applies styles to an element when in fullscreen mode.
|
|
|
|
- Use the `:fullscreen` CSS pseudo-element selector to select and style an element that is displayed in fullscreen mode.
|
|
- Use a `<button>` and `Element.requestFullscreen()` to create a button that makes the element fullscreen for the purposes of previewing the style.

```html
|
|
<div class="container">
|
|
<p><em>Click the button below to enter the element into fullscreen mode. </em></p>
|
|
<div class="element" id="element"><p>I change color in fullscreen mode!</p></div>
|
|
<br />
|
|
<button onclick="var el = document.getElementById('element'); el.requestFullscreen();">
|
|
Go Full Screen!
|
|
</button>
|
|
</div>
|
