CSS 3 Animation AJAX Loaders

After seeing some example of CSS 3 animating “AJAX Loaders” on another site (I think sitepoint.com) I thought it would be fun to make some of my own.

These “AJAX Loaders” are completely styled and animated with CSS 3. They take advantage of new CSS 3 properties like animation, keyframe, and transform so they won’t work in older browsers like I.E. 9-6. If you need fallback support for older browsers I’d recommend using modernizr to check for browsers that don’t support CSS 3 animations and fall back to an animated GIF for those browsers. You can find more information on how to use modernizr for fallbacks here: http://modernizr.com/docs/#features-css

If you need animated GIFs for your fallback you can find a great generator here: http://www.ajaxload.info/ One of the GIFs was the inspiration for the Pac-man example below.

Note: For some reason Opera won’t animate the mouth in this one. I’m not sure why.

Here’s the HTML for this example

<div id="loader5wrapper">
    <div id="loader5">
        <span></span>
        <span></span>
    </div>
    <div id="loader5pellets">
        <span></span>
        <span></span>
        <span></span>
        <span class="ghost">
            <span>
                <span></span>
                <span></span>
                <span></span>
            </span>
        </span>
        <span></span>
        <span></span>
        <span></span>
        <span class="ghost">
            <span>
                <span></span>
                <span></span>
                <span></span>
            </span>
        </span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
    </div>
</div>

Here’s the CSS for this example
