Advanced Visual Animations with CSS Keyframes

Designmodo is has shared with us an article: Playing with CSS3 Animations, which is a personal experience he had while trying to build advanced visual animations with CSS keyframes. We will create a simple fluid menu based on four squares. Clicking on one of them will display an overlay showing related content, closing the overlay will reverse the process showing the default menu. All delays will be managed directly with CSS — no javascript timeout().

All demos have been tested on Chrome, Safari, Firefox, Opera, IE11 and IE10 (also on iOS). They are not intended for production; they are simply provided as tangible case studies. Additionally, you may have to implement some fallbacks for users (especially those using old IE browsers), something beyond the scope of this article.
