Colors Moving Changing JavaScript





Save the Below JavaScript code in notepad with .html extension. Open that file with browser and  see the magic. The colors are moving on the browser. 


JavaScript: 





<html> 
<head> 
<title>Animated Fullscreen Plasma with JavaScript</title> 
<style type="text/css"> 
body{
background:#000;
color:#FFF;
margin:0;
overflow:hidden;
padding:0;
}
address{
bottom:10px;
font-family:Georgia,sans;
font-style:normal;
position:absolute;
right:10px;
text-align:right;
}
a:link,a:visited{
color:#CCC;
}
a:hover{
color:#FFF;
}
td{
}
</style>
