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; }
Permitted properties
Rules with ::cue
in their selectors are limited to using only CSS properties from the following list:
background
and its longhand propertiescolor
font
and its longhand propertiesline-height
opacity
outline
and its longhand propertiesruby-position
text-combine-upright
text-decoration
and its longhand propertiestext-shadow
visibility
white-space
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); }
