Glowing Halo Animation
A very cute little halo animation using CSS3 animation and keyframe properties. Its basically a simple ring that is made using box-shadow property and is scaled using the transform properties to give it a perspective and a 3D look.
Using keyframes, it's box-shadow and scale properties are animated to make it look like its glowing and hence, creating the effect of a halo. Take a look at the code and play with it as much as you like. :)
