@samccone I think the ripple is the wrong size though :(

oh shucks 😢

word word @notwaldorf so the ripple centering was simple enough... however I have run into an interesting issue with a var( inside of a calc .. inside of a @keyframes def ... it looks like it is not being translated at all.. which makes moving the check box to the center difficult (see impossible) since the position of the checkbox is being set "finally" via the animation. 🎲

This seems to be a limitation around the css var shim that we have in place 🐐

Any thoughts on this?

Gonna throw @sorvell at this one and see what he says 🎈

Polymer's custom properties cannot currently be consume in @Keyframe rules. Filed Polymer/polymer#2399 to track progress on fixing this.

@samccone Doing some cleanup -- can I close this PR until the Polymer fix is ready, and then you can maybe re-open it/re-visit then?

[notwaldorf]
