Allowable properties

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

color (en-US)
opacity (en-US)
visibility (en-US)
text-decoration (en-US) and its longhand properties
text-shadow (en-US)
background (en-US) and its longhand properties
outline (en-US) and its longhand properties
font (en-US) and its longhand properties, including line-height (en-US)
white-space (en-US)
text-combine-upright (en-US)
ruby-position (en-US)

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 | (en-US) ::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);
}
