* STROKEWIDTH = 3px

* ARCSIZE = 270 degrees (amount of circle the arc takes up)
|
|
* ARCTIME = 1333ms (time it takes to expand and contract arc)
|
|
* ARCSTARTROT = 216 degrees (how much the start location of the arc
|
|
* should rotate each time, 216 gives us a
|
|
* 5 pointed star shape (it's 360/5 * 3).
|
|
* For a 7 pointed star, we might do
|
|
* 360/7 * 3 = 154.286)

/**
|
|
* 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.
