/**
* IMPORTANT NOTE ABOUT CSS ANIMATION PROPERTIES (keanulee): * * iOS Safari (tested on iOS 8.1) does not handle animation-delay very well - it doesn't * guarantee that the animation will start _exactly_ after that value. So we avoid using * animation-delay and instead set custom keyframes for each color (as redundant as it * seems). * * We write out each animation in full (instead of separating animation-name, * animation-duration, etc.) because under the polyfill, Safari does not recognize those * specific properties properly, treats them as -webkit-animation, and overrides the * other animation rules. See https://github.com/Polymer/platform/issues/53. */
