Graceful Exits   
 
The filters extension to CSS can create dramatic special effects and transitions when coupled with DHTML. For example, the code below creates a transition (a dissolve) similar to what you can achieve with PowerPoint.

<SCRIPT FOR=window EVENT=onload LANGUAGE=Javascript>
dissolver.filters[0].Apply();
dissolver.innerHTML = "<img src=dali.jpg>";
dissolver.filters[0].Play();
</script>
<div id="dissolver" style="position:relative;
width:347; height:330; top:20; left:30; filter:revealTrans (transition=12,duration=8)">
</div>
