Content may be king, but style takes time!

But making the design of the site my own... Oomph, that's killing me. There are a bajillion jpgs in the theme that I want to use as a base. But that did allow me to do one thing: I got to get rid of at least four jpeg files by replacing style commands like this:
background: url(images/title_top.jpg) no-repeat center top;
with style commands like this:
background-color: white; border-left: #a6b6b6 1px solid; border-right: #abb5be 1px solid;
Whee! The pages load faster, and there's less for me to manage. I'm so happy!
