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; }
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 longhand properties apply to each cue individually, to avoid creating boxes and obscuring unexpectedly large areas of the media.

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