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;
} Only a small subset of CSS properties can be used in a rule with ::cue in its selector:
coloropacityvisibilitytext-decoration and its longhand propertiestext-shadowbackground and its longhand propertiesoutline and its longhand propertiesfont and its longhand properties, including line-height
white-spacetext-combine-uprightruby-positionThe 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.
::cue | ::cue( <selector> )
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);
