CSS3 introduced a novel concept, the ability to specify multiple, layered background images. This allows you to build up an image using smaller parts to create a more complex image. This feature allows you to have one single element instead of one for each image, it also means you don’t have to worry about z-indexing as it is automatic. In this tutorial we’ll be creating an animated header using layered background images. We’re going to then apply an animation to position everything and add some interactive elements to finish it off.
