There's been little interest in outline font rendering, but text-outline is one of the supported CSS properties in the WebVTT spec, and US a11y regulations require an outline font style be available. This bug is about implementing text-outline or something equivalent for WebVTT purposes.
I don't think we should implement a 'text-outline' property, the types of effects you need would be better covered by 'text-stroke' and 'text-fill' properties. That's a better, more general model I think. The 'text-outline' property was in CSS3 Text but it's no longer there, I'm not sure if it's been dropped completely or lives on the in the mind of the spec editors. I think in this case it should be dropped from the WebVTT spec since it's not an existing CSS property. What does "US a11y regulations require an outline font style be available" mean? Just that there needs to be a way of having text that contrasts with the background?

Text-stroke would probably work fine. As Cameron pointed out, you really want the stroke to happen after the fill, if you can't otherwise control it. The general requirement is that some sort of outline font rendering be selectable. I don't care what css property we end up using for that, text-outline is just what the webvtt spec currently specifies.

Is this still relevant? We have -webkit-text-stroke (see bug 1248708 and dependencies), and also paint-order (bug 1435684), which AFAICS should provide the functionality that's requested here.

Severity: normal → S3

In the current spec at https://w3c.github.io/webvtt/#css-extensions, neither text-outline nor -webkit-text-stroke, its standardized counterparts stroke-* from the Fill and Stroke spec, or paint-order apply to WebVTT.

So I think, at this point it makes sense to close this bug and rather file an issue against the WebVTT spec to discuss whether the standardized properties mentioned above should apply.

Emilio, Jonathan, what do you think?

I think closing this is fine. Authors can already style the WebVTT cues with ::cue and apply these properties, and I don't think they should apply by default FWIW...

(In reply to Emilio Cobos Álvarez [:emilio] from comment #5)

I think closing this is fine. Authors can already style the WebVTT cues with ::cue and apply these properties, ...

As noted earlier, the WebVTT spec currently doesn't allow those properties in ::cue. So I've now filed https://github.com/w3c/webvtt/issues/545 for adding them.

... and I don't think they should apply by default FWIW...

Expressed myself ambiguously. I meant that they should be allowed to be used in ::cue (and its functional variant).
