Actually, the timestamps allow for Karaoke markup IIUC.

A cue such something like the following can work:

--> STYLE
::cue(:before) {
  color: red;
}
::cue(:after) {
  color: grey;
}

00:00:00.000 --> 00:01:00.000

Right now, you need that CSS to be interpreted by a Web browser. But I
agree with Carlos that we need a solution that is independent of the
Web and provides the styling as part of the WebVTT file:
