Template doesn't look right in Joomla!

[abrodski]

Hello!

I'm new to Joomla! so I might not know something about changing the default template for entire site.
Usually I use Firefox browser (in XP Pro) for both back and front ends.As you know,the default template after the installation is rhuk_ milkyway.But it doesn't look too great.So I changed it to ja_purity.After that IN FIREFOX everything looked right,but when I opened the site in IE 8,some stuff looked wrong.I'm talking about how everything was positioned.It was kinda messed up.
I could improve something by,say,adjusting the position of something,but mostly it didn't help,so I just switch back to milkyway template and everything got back to normal in BOTH browsers.
Why this happened? and another question is...
Does it matter in which browser I work in back end in regard to how my site would look in front end? Maybe because I created content in Firefox that's why in IE 8 it looked wrong or those things aren't connected?

I suggest you add a IE7 compatibility mode tag into the HEAD of your document (make sure it is the first meta tag there). That will fix it until ja_purity has been updated for IE8.

And to answer your other question: it makes no difference what browser you use to do your work on the backend.
