Just place the "px" in the expression...

As in:

top:expression((document.body.scrollTop + 'px'))


<div style="position:absolute; top:expression((document.body.scrollTop +
'px'))">The div</div>

Subject: [javascript] scrollTop in integer and top in px


I was trying to make the top property of a certain div relatively to body's 
scrollTop value. Here's what I did:

top:expression(document.body.scrollTop)

But later I found out that scrollTop has a value of integer, while top will
also 
has value in px. How do I transform scrollTop from integer into px??
