I'm trying to swap out the YouTube icon for the YouTube red square background/white playbutton.
These icons are used in a Zurb Foundation 4 site. You can see the defaults working just fine here: http://www.getty.edu/visit
I can't post the busted one, as I don't have a publicly available dev area, but I posted the svg code below if you want to swap out an existing webicon and give it a spin.
I downloaded the vector art from YouTube. I opened the fc-webicon-youtube.svg and started there:
When it displays with the .medium class, the background is blank.
When I open the .svg file in a text editor, I see that there's some extra stuff, like a width and height setting in the tag, a tag wrapping the gradients and such. When I remove those, the icon resizes down too small, and begins to repeat. I also noticed that the SVG code AI spits out doesn't match the other webicons, so... curious if this is the new Adobe Illustrator screwing things up?
If I go into FireBug or Developer Tools and set the background-size: 100%; to have an !Important tag, it works (and none of the other webicons break). Weird.
I've attached the svg code here.
