Web developers have been immersing themselves into CSS3-based designs. Transition animations along with CSS keyframes have opened the door to many possibilities. 3D animation was never optimal outside of Flash-based websites. However the further advancements in JavaScript along with CSS3 have created a new code toolbox for web designers.
I’ve put together a number of fantastic open source code samples using 3D animation effects. Many rely solely on CSS3 while others are a mix of CSS and JavaScript. Keep in mind that people using older web browsers may not be able to fully appreciate your 3D animations. But that doesn’t mean you should ignore the practice! As more people upgrade to newer browsers there will be greater support in the years to come.
