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?

yea but sometimes it even did that with internet explorer for my friends, but is there anyway i can make it so other people can view it without having to have internet explorer?
