margins screwing up in other browsers? Options

[blackangel6669]

I'v got this as the code for the avril skin i'm using, thats what it came with:

<!-- begin code provided by createblog.com --><br /><div style="overflow:<br />auto;width: 395px;<br />height: 275px;<br />margin-top: -315px;<br />margin-left: -315px;"><br /><!-- end code provided by createblog.com -->

And its aligned perfectly when I view it from home, where I have internet explorer. But at my mom's she can't use that browser, so I tried it in Netscape and Mozilla. But then the blog is like way to the right. I even played around with the numbers, and it never goes completly to the left, or even close. Negative, close to zero, AND positive numbers stay to the right. its kinda freaky. Is this just the browsers I'm viewing it in, and is there anyway to make it look RIGHT when peopl view them from these browsers?

I had the same problem with the last layout I used, only I saw it in the correct place and my friends saw it in all kinds of different places.

Any idea?

thats exactly wats goin on lol i'm glad you could tell me more about it, only thing is.....if this is happening with like every layout...some people should really be working on a way around it. I'm far too unexperienced in html to do it myself, but idk.....shouldn't somebody be trying to figure that out?? Maybe I could send it to the Xanga people and ask them for help..only 1. there busy and probly wouldn't even reply and 2. i'm not sure if they like this whole other skin thing, sence we kind of already have to go around alot to put our own up. Like taking away the annoying footers n stuff....they probably wouldn't want to help us.

so...what to do what to do? i have no idea how to fix this and i'm not sure anybody else does.
