Hi all,
I'm (needless to say) relatively new to CSS3 and I'm having trouble with aligning content.
I have a page with a jQuery UI Tabs module in it. When I display it on the page, it comes out looking like this:

EDIT I know it's a terrible screenshot, but I'll just say, the Tab box is left-aligned on the page.
I've tried to use the text-align property on the <td> and the <div> containing the content, I even got so desperate I tried the HTML <center> tag, all to no avail.
Does anyone have a sure-fire way of centering content with CSS?
Thanks in advance! :)
