Small demo of animated CSS Mask Icons. Note: It uses the non-standard CSS masks that are only implemented in WebKit without a spec. I don’t wanna go into discussing if that’s ok or not, instead I just like to experiment with them because I think you can do cool stuff and hopefully one day it will become standard. Update: Happy that there is now a CSS Masking Spec.
Using CSS masks for icons would have the benefit of being able to create a large icon-set and easily swap textures, colors, shadow effects. And also animate them. Basically everything you can do with CSS backgrounds. It could also be used for other stuff like tooltips, speech bubbles, funky shaped buttons and so on.
The basics of this demo goes something like this:
So ya, basically you can mask a mask, combine multiple masks or even do the opposite depending if they overlap or not. In total there are a dozen mask-composite options that I’m not quite sure what the exact difference is. I just tried them all till it worked like I wanted. ;-)
