How to increase the width of my site

Your current width is 960px, which is standard.

You can adjust the width using this in your custom css:

#container {
    width: 1160px;
}

Just change the 1160 to whatever you like.

Note, you will probably want to check and see how this affects your site on various monitor resolutions. With narrower monitor resolutions, it might force a horizontal scrollbar across the bottom of the page.

You have been warned ??

Thanks Josh, I am desperately in need to increase the size a bit but have not seen where the code is located, can you throw more light?
this is my style.css
