Help with CSS Fluid design but not 100% width

[gwmbox]

Hi guys

Had a look at the CSS Templates at

http://www.dynamicdrive.com/style/layouts/category/C9/

and in particular

http://www.dynamicdrive.com/style/la...1-fixed-fluid/

But what I want to know is how do I get the same fluid main content area (right side) but restrict the overall page width to a max-width or even a percentage - like 90%?

Thanks

If you're using the same class/id names, just add this to your CSS

#maincontainer
{ 
      width: 90%; 
}

replace the 90% with whatever percentage you want or with pixels etc...
