Microsoft IE 4.0
Dynamic Style Sheets
CSS properties can be changed at run time:
<H1 onMouseOver {colour: red;} onMouseOut {color=yellow}>
A more elegant way is to store the Javascript code in the document HEAD (or externally)
CSS Positioning
Elements can be positioned absolutely or relative to each other
<IMG SRC="smiley.gif" : top: 25% ; zindex=1>
<DIV zindex=2>Text on top of image</DIV>
