Post Your Site's Interesting CSS Customizations

Thought I'd share a few of the CSS customizations we've made to our site which may be helpful to others, ...with the hope that a few of you would post your favorite customizations too. Please include your site's URL.  
(Would also welcome comments from Hoop if any of these need adjusting.)
