Intent to implement and ship: support ::cue pseudo-element from document.

2017-03-29 Thread bechen 
Summary:
We are going to support ::cue(with no argument) pseudo-element for webvtt.
It allows styling the webvtt subtitle/caption text during video playback.

Bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1318542

Spec: https://w3c.github.io/webvtt/#the-cue-pseudo-element

Platform coverage:
All platforms

Estimated or target release:
Firefox 55

Preference:
media.webvtt.pseudo.enabled, default is true.

DevTools bug:
None.

Do other browser engines implement this?
Yes, chrome, safari, opera

Web Developer Use-Cases:
write the ::cue style block in the document, then ::cue rules will be applied 
to the .vtt subtitle. Note that the ::cue style block can only appear in 
document, not in vtt file (not support yet).

::cue {
  ...
}


 


Tests:
web-platform/tests/webvtt/rendering/cues-with-video/processing-model/selectors/*
Tests under the folder are disabled now, I'm going to enable/fix them.
