I designed the DIY Theme specifically to be easy to customize, and am working my way through a series of posts to help beginners learn to do that. The first post is up at my main site: The easy way to learn CSS and customize your blog theme. I hope it’s helpful! If you’re building a site you may still be looking for a web host. I HIGHLY recommend Hostgator. I use them for all my sites and their support is totally awesome! I’ve worked with a lot of hosts and they are hands-down the best.
