Hi, On this page: http://www.trevorhartman.com/Retna/ I'm trying to center the content of both the upper and lower frame. The difference between the frames is the top has a scrollbar and the bottom does not. I think this causes the page width to differ, resulting in different center (the two don't match up). Here is the centering code for the upper frame: div#content { width:841px; position:absolute; top:0px; left:50%; margin-left:-420px; } On the lower, I tried doing margin-left:-426px; which looks fine in Safari and Mac FF, but Win scrollbars are a little wider so it doesn't line up right. Any way around this? thanks, Trevor
Avoid at ALL costs absolute positioning unless it is absolutely necessary. It "works" but you'll thank me later. There's better ways to center content on a page. see: http://www.bluerobot.com/web/css/center1.html anyway, if you want scroll bars to appear ALWAYS even when they are not needed, you need to use the overflow property. add this to your bottom frame: html { overflow-y: scroll; } And, frames are really out dated too. consider using an include (php, shtml, etc) and dock it to the footer with css instead: http://scott.sauyet.com/CSS/Demo/FooterDemo1.html
