Feature: rgba backgrounds through progid:DXImageTransform.Microsoft.gradient

[gordonbrander]

Might be related to http://github.com/lojjic/PIE/issues/#issue/7.

It would be great to have support for RGBA backgrounds.

RGBA background colors can be approximated in IE through the progid:DXImageTransform.Microsoft.gradient filter. If you give the startColorStr and endColorStr a hex value with 8 places, the first two will define opacity (a live demo can be seen at http://CSS3please.com).

Gordon, thanks for reporting! You have the honor of being the first to open a ticket. :)

I assume you're talking about rgba for solid background-colors. Actually PIE should already support this, as long as you're using the -pie-background property (it won't work in the standard background property because IE doesn't give access to values of standard properties it doesn't know how to parse). I'll double-check when I get a chance this weekend, but if you have a testcase that would be great.

(Hmm... just noticed GitHub's issue tracker doesn't allow attachments... any ideas on tracking testcases, screenshots, etc. with tickets?)

FWIW, using the progid:DXImageTransform.Microsoft.gradient filter shouldn't be necessary, because PIE renders the background using VML which allows opacity on the fill as a native attribute.

Aha! Makes total sense. Sorry for the bogus report.
