ZEPPELIN is an experiment trying to create a glass text effect (refractive index) with CSS3. The refractive index effect is achieved by using two background images on top of each other. The underlying one get’s scaled down a bit and the top one get’s cutout by the text using -webkit-background-clip: text. For the embossing effect a -webkit-text-stroke with a low opacity is used. Something to keep in mind, animating clippings, text-shadows, transparency can make your CPU spike, it’s not just Flash, CSS can be misused too. So the animation is not looped, only on hover.
This experiment is inspired by Trent Walton’s example.
