1350147 - Consider removing the -moz-bound-element pseudo-class.

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, enhancement)

Description

[Emilio Cobos Álvarez (:emilio)]

I was going through pseudo-classes for bug 1350140, and leaving comments with the missing ones, when I saw the :-moz-bound-element pseudo-class.

This is somewhat tricky to implement in Stylo (doable still, I guess), but it seems completely unused, both in mozilla-central and in the addons code.

We should consider removing support for it.

Not sure if I should ask for review... Should I send an intent-to-unship or something?

Since this is something exposed to web content, we probably should have an intend to unship.

So this was added in bug 71261 (quite old, hmmm)

Given it is not used anywhere, I think it's okay to remove.

I'd like to document it's removal at https://developer.mozilla.org/en-US/docs/Web/CSS/:-moz-bound-element, though first need to create that page.

Jean-Yves, do you believe it's worth the effort or should we rather remove references to it from MDN?
Emilio, what was the pseudo-class actually meant for?

[David Baron :dbaron:]

If it wasn't documented already, it seems better to just leave it undocumented.

Comment 9

[Emilio Cobos Álvarez (:emilio)]

Right, I agree with David.

I haven't seen any reference in MDN apart from the one at https://developer.mozilla.org/en-US/docs/Web/CSS/Mozilla_Extensions#Pseudo-elements_and_pseudo-classes.

Ok, I've removed it from the reference page.

For completeness I've mentioned its removal in the 55 developer release notes:
