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:
color
opacity
visibility
text-decoration
and its longhand propertiestext-shadow
background
and its longhand propertiesoutline
and its longhand propertiesfont
and its longhand properties, includingline-height
white-space
text-combine-upright
ruby-position
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); }
