hecster2k Nervous Wreck (II) Inmate From: sj, ca, usa Insane since: Feb 2002	posted 02-12-2002 19:24 ok, here's my dilemma: I created a floating toolbar that aligns to the bottom of my page. when i resize the page, it re-aligns by recapturing the clientHeight and setting the div's top property. so that part works. second part is what i'm having trouble with. i need to be able to calculate the overall height of the document (not the window) so that i can realign the toolbar accordingly. if i have a window open that is 100x100, for example, and align a 5px toolbar to the bottom, it would set the top at 95px. but if it scrolls, the toolbar is scrolled too. i need to align it to the bottom again, but can't capture the right values.

This means that the toolbar will always be visible. You need to add the scroll distance to your vertical positioning of the toolbar. For IE: y+document.body.scrollTop For Netscape: y+window.pageYOffset

Supposedly...

position:fixed;
top:95px;

should also work, and won't need to be updated when the document is scrolled. If it works in new browsers, though, it won't work on old ones.

Addendum:

I am getting some of my pages XHTML1.0 compatible and I found an interesting behavior in IE when using scrollTop.

For this doctype,
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

document.body.scrollTop no longer works but document.documentElement.scrollTop does.
