Embarassingly basic question

[E.M.P.]

Hello, I've been lurking here for a while, picking up great tips on how to match my SmugMug site (for client proofing) to my main site.

So far, I'm pretty happy with how well I've been able to match the two. However, there's a horizontal line under my navbar that I would like to make just 800 pixels wide. Unfortunately, all I've been able to do on SmugMug is make it all the way across the screen.

I know this is a ridiculously easy question, but I haven't been able to figure out the answer. Can someone please tell me how to make my line just 800 pixels wide? You can see what I mean if you compare my website (www.elizabethmorrisonphotography.com (http://www.elizabethmorrisonphotography.com)) to my smugmug site (smugmug.elizabethmorrison.com).

Thanks!

Just add this CSS to your site-wide-customization CSS box:

#navcontainer {width: 800px; margin: 0 auto;}

Thank you so much -- it worked perfectly!
