Cross fading images : One image to another with a timer (Webkit/Firefox 5/IE10 only, transitions and animations)

You could implement this by using Javascript to toggle classes with a delay – that would allow older browsers to still have the images change. As we are looking forward though, we’ll use CSS keyframes.

  1. Start with demo 1
  2. Use CSS keyframes to define two states, one with top image transparent, one with it opaque.
  3. Set the animations number of iterations to infinite

Everything’s the same as Demo 1, but I’ve added this to the CSS and removed the hover selector

@keyframes cf3FadeInOut {
	0% {
	45% {
	55% {
	100% {

#cf3 {
	animation-name: cf3FadeInOut;
	animation-timing-function: ease-in-out;
	animation-iteration-count: infinite;
	animation-duration: 10s;
	animation-direction: alternate;

To make sense of that, I’ve defined 4 keyframes, specified that whatever has this animation attached will be opaque for the first 45%, then transparent for the last 45%. The animation will repeat forever, will last 10 seconds, and will run forward then backwards. In other words, image 1 will be visible for 4.5 seconds, followed by a 1 second fade, followed by 4.5 seconds of image 2 being visible. Then it will reverse, meaning that image 1 and 2 will both be visible for 9 (4.5 x 2) seconds each time.

Demo with multiple images

This time I’ve created an animation that goes from 0 to 1 opacity, then staggered the animations so only one is visible at once. It’s not great, but it is maybe a start. Any suggestions on how to make this better would be gladly received!

	#cf4a img:nth-of-type(1) {
 		animation-delay: 0;		
	#cf4a img:nth-of-type(2) {
 		animation-delay: 2s;		
	#cf4a img:nth-of-type(3) {
 		animation-delay: 4s;		
	#cf4a img:nth-of-type(4) {
 		animation-delay: 6s;
