where to find the css file of PAGE_CONTAINER

[typostudy]

...
                <div id="content" class="{$contentTemplate}">
                    <div class="pageWidth">...

Above code is from templateAGE_CONTAINER, my question is:
where to find this the defination of .pageWidth? seems there is no PAGE_CONTAINER.css file.

Search the templates for pageWidth

Thanks. I saw template->appearance->Style Properties: General,

min-width: 940px;
_width: 976px;
_margin: 0 auto;

But from the front end, I use firebug, I saw:

.pageWidth
{
 margin: 0;
min-width: 950px;
width: 950px;
margin: 0 auto;
 
}

so how come?
