The ::cue CSS pseudo-element matches WebVTT cues within a selected element. This can be used to style captions and other cues in media with VTT tracks.

::cue {
  color: yellow;
  font-weight: bold;
}

Allowable properties

Only a small subset of CSS properties can be used in a rule with ::cue in its selector:

The properties are applied to the entire set of cues as if they were a single unit. The only exception is that background and its shorthand properties apply to each cue individually, to avoid creating boxes and obscuring unexpectedly large areas of the media.

Syntax

::cue | ::cue( <selector> )

Example

The following CSS sets the cue style so that the text is white and the background is a translucent black box.

::cue {
  color: #fff;
  background-color: rgba(0, 0, 0, 0.6);
}
