FrameworkStyle

Skins

Packaged player designs that include both UI components and their styles.

<Player.Provider>
  <VideoSkin>
    {/* wraps the Media component */}
    <Video src="video.mp4"></Video>
  </VideoSkin>
</Player.Provider>

Packaged vs. ejected

When you choose a skin you have two options for how you use it: packaged or ejected . It’s usually easiest to start with a packaged skin and later eject its internal components into your project when you need more customization.

Packaged Ejected
Single component Many UI components
Limited customization Complete customization
Future design updates auto-applied by bumping the version Future design updates manually applied, or intentionally ignored

Example of packaged 

  <Player.Provider>
    <VideoSkin>
      {/* ...Media... */}
    </VideoSkin>
  </Player.Provider>

Skins, features, and presets

Each skin is built with specific features in mind. For example, a video skin renders fullscreen and picture-in-picture controls. An audio skin doesn’t. The features associated with a skin are called a feature bundle .

Feature bundle Available skins Import
videoFeatures <VideoSkin>, <MinimalVideoSkin> @videojs/react/video
audioFeatures <AudioSkin>, <MinimalAudioSkin> @videojs/react/audio
backgroundFeatures <BackgroundVideoSkin> @videojs/react/background

Styling

There are currently two options for styling:

  • Vanilla CSS where you import the stylesheet in your app. This is the default.
  • Tailwind where you eject the skin and use Tailwind classnames in your app.

Current limitations

  • In both style systems we assume a 16px root font size and we use rem units for sizing.
  • The default font stack includes Inter (because it’s awesome) but we do not load the webfonts for you. If they are not available then system fonts are used.

These only apply to ejected HTML and React skins:

Vanilla CSS

  • We use a BEM classname structure and every component classname is scoped with a media- prefix.

Tailwind

  • Currently we’re assuming you’re using the default configuration and that’s all that’s supported. With the release of our CLI, this will change, allowing you to specify a custom prefix to the Tailwind classnames. For now, you’ll need to edit the ejected skins yourself.
  • We’re assuming the latest version, currently 4.2.x.
