One of the most versatile ways to improve your blog is by adding CSS rules. CSS stands for " Cascading Style Sheet ". The term "style sheet" refers to the template sections which contain style rules, which affect the appearance of the blog. The term "cascading" refers to how you manage the rules. With CSS, you have no need to edit existing style rules, to make a change. If you define your rules properly, you make higher level rules specific enough so they cascade over lower level rules .
