Yep that looks perfect. I did some testing with a simple div and other CSS properties, and so far it's worked perfectly I'm glad it's being added to the CSSplugin.

Thank you so much for a clear and simple solution Hopefully in the near-future greensock's Css plugin will be able to support css variables - until then thanks for the quick and awesome solution!

Just want to say that I've posted the same question on StackOverflow, but figured I would post it here too I'm really into Google's Polymer and I love GSAP - and so far I've been using the two in conjunction without a hitch. Unfortunately I have now hit a problem - how do I use GSAP (TweenMax to be specific) with custom css variables? For example: To change someCssProperty of someElement I would TweenMax.to(someElement, 1, someCssProperty: "value"); but the someCssProperty part becomes an issue when I'm trying to animate a css variable, which take on the form --some-custom-css-variable I have tried to use TweenMax.to(someElement, 1, --some-custom-css-Property: "value"); (obviously gives me errors) and I also tried to use TweenMax.to(someElement, 1, "--some-custom-css-Property": "value"); (quotes around the some-custom-Css-property) - however this results in no change/animation and an invalid tween value error message on the developer console. So the question is: how would I go about animating custom css variables with TweenMax (GSAP)? Thanks for any help EDIT: I have tried using classes through TweenMax.to("SomeElement", 5, {className:"class2"}); But this changed the element style as if I had declared it in css with a SomeElement:hover {} style (as in it does not animate, just changes immediately)
