<!-- This div is the element we are animating -->
<div id="urgent"><h1>Red Alert!</h1>The Web server is under attack!</div>
<!-- This is the animation script for the element -->
var e = document.getElementById("urgent");         // Get the element object
var colors = ["white", "yellow", "orange", "red"]  // Colors to cycle through
var nextColor = 0;                                 // Position in the cycle
// Evaluate the following expression every 500 milliseconds.  
// This animates the background color of the DIV element.
setInterval("[nextColor++%colors.length];", 500);
