Answer 1

The "ribbon" DIV that is getting cut into is essentially at position 0 on the z-axis. In order to have it not get cut by the other DIV rotating along the y-axis, you need to push the "ribbon" DIV back on the z-axis by a distance at least half the width of the rotating DIV. For example, if the rotating DIV has a width of 100px, then apply the following CSS to the "ribbon" DIV:

-webkit-transform: translate3d(0, 0, 50px)
