I see the same layout problems going to https://m.clippercard.com/ on Firefox desktop. It's probably just an evangelism issue since I see loads of webkit-prefixed styles.

Specifically they have this in their CSS:

transform:perspective(0) translate(-260px, 0);

And we don't recognize this as a valid transform value. The perspective(0) part causes the CSS property to get ignored and so the translate is thrown out as well.

Hmmm that looks like a bug of Gecko.
http://dev.w3.org/csswg/css-transforms/#transform-property

transform may have multiple list of values. 

Though I could not find the appropriate bug for it
https://bugzilla.mozilla.org/buglist.cgi?quicksearch=transform%20perspective&list_id=12312590

Or did I miss something?

oh more subtle indeed.

This would work
	transform:perspective(1px) translate(-260px, 0);

But not these
	transform:perspective(0px) translate(-260px, 0);
	transform:perspective(0) translate(-260px, 0);

And indeed the spec says:

> The value for depth must be greater than zero, otherwise the function is invalid. 
— http://dev.w3.org/csswg/css-transforms/#funcdef-perspective

Good luck with that and WebKit implementing it.
made a test case

so this one is NOT fixed by layout.css.prefixes.webkit;true

Comment 6

[Mike Taylor [:miketaylr]]

I filed https://github.com/whatwg/compat/issues/48 to spec the "zero perspective transform quirk", it's probably something we need to implement. Before filing a bug on that, I want to understand why the menu is open (maybe same issue, dunno).

[Mike Taylor [:miketaylr]]

(OK, yep, that seems to be the main issue here, like Karl said in Comment #4)

Karl, can we try to do outreach while we get this specced and (possibly) implemented?

Comment 8

[Karl Dubost💡 :karlcow]

yup.
I (cheekily) tested with different values to see what could work

I will find contacts. Switching to needscontact.
