On this page you have the option to "Click to see how the images look in a black background..." then the background goes black. You can click again to make it white again. How are you able to do that?

This is the code used:


<script language="JavaScript1.2">
function changesettings(){
if (document.all){
if (document.body.style.cssText==''||document.body.style.backgroundColor=='white')
document.body.style.cssText="background-color:black;color:white;background-image:url()"
else
document.body.style.cssText="background-color:white;color:black"
}
}
</script>

<a href="changesettings();">Click here</a>

Is the code used to change the backdrop. It only works in Internet Explorer.

Im still a little confused. When I tried to use it, it went to a new page.
