Bug ID: 25637
Summary: [WebVTT] Make the padding at the edges of the video
overridable using CSS
Product: TextTracks CG
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: WebVTT
Assignee: dave.null@w3.org
Reporter: philipj@opera.com
QA Contact: public-texttracks@w3.org
CC: philipj@opera.com, silviapfeiffer1@gmail.com
We currently have:
The 'padding-top' and 'padding-bottom' property on the WebVTT cue background
box must be set to '1.5vh' or another user-agent-defined number to define a
padding at the edges of the video into which cues will not be placed. In
situations with overscan, this padding should be sufficient to place a cue
within the title-safe area. In the absence of overscan, this value should be
picked for aesthetics (to avoid text being aligned precisely on the top or
bottom edge of the video, which can be ugly).
The 'padding-left' and 'padding-right' property on the WebVTT cue background
box must be set to '1.5vw' or another user-agent-defined number to define a
padding at the edges of the video into which cues will not be placed. In
situations with overscan, this padding should be sufficient to place a cue
within the title-safe area. In the absence of overscan, this value should be
picked for aesthetics (to avoid text being aligned precisely on the top or
bottom edge of the video, which can be ugly).
It would be very nice if this were exposed to CSS, maybe with a default of 5vh
to match the default line height. For the overscan situation, the user agent
can simply have a user agent stylesheet with higher priority than author CSS.
