feature request - gradient backgrounds #30

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
-moz-linear gradient(),-moz-radial-gradient() and
-webkit-gradient(linear|radial) all exist

I know that it is possible to use either -ms-filter or vml eg
<v:rect fillcolor="red">
<v:fill ID="grad" color2="blue" type="gradient" angle="180">
</v:rect>

which will do a gradient (the example given will transition from red at the
top to blue at the bottom - change angle="90" to do a left to right gradient)

I just can't work out how to generate this from a -moz-linear-gradient

Any help gratefully received

The combination of Microsoft's gradient implementation with curved corner 
doesn't work. You just get a square. It would be nice if it would work.

I can definitely see the issue here:  

Because the script is currently zapping the target element's 
background/borders, and replaces with a RECT/FILL -- the script has a 
responsibility to ensure that ANY known background schemes are passed to the 
VML fill, including linear-gradient.

Possible resolution:

Sniff for liner-gradient on background-image, where CSS3 has it, via 
currentStyle -- the tricky part is parsing it into something VML can understand 
-- there seems to be a few competing methods that all have slightly different 
functionality ... Fortunately, a cursory review of the MSDN docs implies that 
VML can handle pretty much any kind of gradient thrown at it, both the various 
old and the new css3 standard.

Some references I'll need later:
