Centering Blog

[beebop]

Hi Guys
I'm new to Blogger and could do with some help on something that is really frustrating me! I am trying to get my blog to be centered in the middle of the screen / browser. I want it to be centered horizontally so that there is white space on the left and on the right.
On my screen (1440 x 900) it looks perfect using and internet explorer however it is aligned to the left on mozilla - argh! Likewise, on some friends laptops it looks fine, but on screens that are more "square" it aligns to the left again.
I have traulled the web but having no luck. Thought someone on here MUST be able to help! Thank you in advance
Here is part of the code (please let me know if you need any of the rest):

body {
background:$bgcolor;
margin:0;
color:$textcolor;
font:x-small Georgia Serif;
font-size/* */:/**/small;
font-size: /**/small;
text-align: center;
}
a:link {
color:$linkcolor;
text-decoration:none;
}
a:visited {
color:$visitedlinkcolor;
text-decoration:none;
}
a:hover {
color:$titlecolor;
text-decoration:underline;
}
a img {
border-width:0;
}

This is how you do it:

Located the code that says:

#outer-wrapper {
width: 900px;
margin-right: 0px;
margin-left: 0px;
margin-top: 0px;
margin-bottom: 0px;
padding:0px;
text-align:$startSide;
font: $bodyfont;
overflow:auto; 
overflow-x:hidden; 
}

Change it to:

#outer-wrapper {
width: 900px;
margin: 0 auto;
padding:0px;
text-align:$startSide;
font: $bodyfont;
overflow:auto; 
overflow-x:hidden; 
}

That's all it takes! Let me know if you have any trouble.

I don't know the code too ,but I want to learn it.

Robin - I'm not very good at coding but you can learn sorta by doing somewhat simple little tweaks here and there in the codes that exist.

Truth be told, I'm envious of those who can code really well or even at all!
