Hacking blogger (blogspot) css content

I have been working a little bit with blogger content and have a few tips and tricks that I have learned that a lot of n00b bloggers like and are looking for. I decided to start posting content on different design hacks to help people customize their blog to the way the like it. If there is any feature you are looking for, feel free to post it as a comment and I will work towards creating it. Thanks!
