CSS3 3D Animation

CSS 3D Animation

The introduction of CSS 3 has changed the over all look and feel of the websites. CSS3 animations; transitions and transforms are the most interesting things in CSS3 ie. CSS3 3D animation . CSS transforms allows elements styled with CSS to be transformed in two-dimensional or three-dimensional space. No javascrip, no flash is required for creating 3D animations. It works well in latest browsers and just fine in less capable browsers.

CSS3 3D animation Explained

While we do CSS3 3D animation, we have to know two properties in CSS 3D transforms. One is “Perspective”. To activate 3D space, an element needs perspective. This can be applied with transform property, with the perspective as a functional notation

transform: perspective

Second thing is 3D transform functions. 3D transform uses the same transform propety used for 2D transforms.

CSS3 3D animation Example

Here I am going to give an example of 3D animation using a Mobile. When we hover the phone image it rotates and we are able to see the other side of the mobile.

CSS for CSS3 3D animation Explained

In the first place, we are enabling the 3D transforms. We are using two DIVs for the two sides of the mobile. And by using backface-visibility: hidden, we are hiding the DIVs when they are flipped. We animate the transitions with transition: 0.8s. With the class ‘mobile-back’, we are flipping the DIV which contains the other side of the mobile, to 180 degree as its default state. When we hover the container, we’ll flip the front side and hide the DIV and at the same time, we’ll flip the second container with the back side of the mobile.
