In the non-region case:

If you explicitly specify the width of your cue and the text is much
smaller than the width, the background will still cover the fully
specified width.
If you do not specify a width, then the cue with is determined
automatically based on the text width and the background will only be
on the width of the text.


In the region case:

The non-region case background on ::cue still applies.

However, there is now also a region box whose size is explicitly
determined (width/height). You can set a background color on that box
with ::cue-region . That background covers the full width of the
region no matter the width of the cues or cue text inside.
As for the height: in the case of scrolling regions, the height is
dynamic and depends on the number of lines that are being rendered.
For non-scrolling regions the height is fixed, so a non-scrolling
region without cues inside with a red background will be a red
rectangle on screen.


Hope that clarifies it?
