File: PosterCircle.css

Abstract: Defines CSS properties for the PosterCircle sample.

          Defines and styles each ring of the cylinder. Applies

          CSS transform and animation properties to these rings.

          Styles and controls the posters on each ring.

/*

    We use three individual animations (x-spin, y-spin, back-y-spin) to create

    the cylinder's 3D rotation effect. The x-spin animation will perform a

    full rotation on the x-axis, we'll use that on the whole set of objects. 

    The y-spin and back-y-spin animations will perform a full rotation on 

    the y-axis in opposite directions, alternating directions between rings.

    We define each of these animations using the "@-webkit-keyframes" rule. 

    Note that since animations will take the shortest path between values

    and a rotation of 0 degrees is the same orientation as 360 degrees, it

    is necessary to specify an intermediate keyframe step that is half way

    around a full rotation. This way the animation will rotate to 180 degrees

    half way through the animation and then continue on to 360 degrees. */
