DIV Layout Problem (browser related), layout looks different in IE and firefox Options

[wicked_pennywise]

Ok, my new div layout that I'm working is coming along great except for one small thing. The div's that I used to put text in all look great in IE...their positioning is spot on in my browser at least. In firefox, they're either 1 or 2 pixels off placement or they're too for the area I designed for them. Does anyone know why they look different in two browsers?

Try not to use margins and percents. That seems to keep them aligned in both browsers for me.
my myspace. I do this:

.divnameofyourchoice{
position: absolute;
left: #px;
top: #px;
width: #px;
height: #px;
z-index: #;
}

<div class="divnameofyourchoice">

stuff stuff

</div>

Try that out for one of yours and see if it aligns the same in both.
