RGB tribute
A simple RGB tribute created using animation and keyframes. There is one div for each circle with colors red, green and blue having 50% opacity to make color mixing and overlaying work. Each circle is given a different animation. This is a very nice example of how we can use CSS to render color mixing. This demonstration will work only in Firefox and Webkit based browsers so make sure you use these browsers.
Take a look at the source to understand more about it. The markup is very simple and the CSS is self explaining.
