<div id="crossfade">
    <img class="bottom" src="images/YourImage.jpg" />
    <img class="top" src="images/YourImage.jpg" />

#crossfade {
#crossfade img {
    opacity: 1;
    -webkit-transition: opacity 1s ease-in-out;
    -moz-transition: opacity 1s ease-in-out;
    -o-transition: opacity 1s ease-in-out;
    -ms-transition: opacity 1s ease-in-out;    
    transition: opacity 1s ease-in-out;

#crossfade {

As you can see, first two images were identified under a <div id></div> and then the #crossfade selector is used to endure the proper layout. A second selector of #crossfade image then sets the opacity to 100% and also adresses browser compatibility and support of the transitions. The last bit of code needed is the #crossfade img. top: hover declaration setting the opacity to 0% upon hover.

And there you have it. A nice image crossfade every time. You may also find interest in this CSS Basics tutorial on using selectors properly. If you have a tutorial request or wish to share one of your own, please send us a message letting us know.
