https://www.w3.org/Bugs/Public/show_bug.cgi?id=18519

           Summary: Add opacity and/or visibility to the ::cue property
                    white list
           Product: TextTracks CG
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebVTT
        AssignedTo: ian@hixie.ch
        ReportedBy: philipj@opera.com

The use case is to hide future parts of the cue with ::cue(:future) { opacity:
0 }.

(It could also be nice to quickly fade cues in and out with CSS transitions
using opacity on ::cue itself, but given that the cue doesn't exist in the
layout before or after its time, it doesn't seem like that can work,
currently.)

The visibility property could be allowed for authors who try that before
opacity, but doesn't allow anything that opacity does not.
