I think it's official. I'm entering into geekdom & reading CSS: The Missing Manual.
A very nice stranger, M.S., helped to motivate me to utilize Cascading style sheets for my website instead of just HTML. I'm learning & it's actually really exciting! The author of this book, David McFarland, is a great teacher! What is CSS? ---> CSS, short for Cascading Style Sheets, a new feature being added to HTML that gives both Web site developers and users more control over how pages are displayed. With CSS, designers and users can create style sheets that define how different elements, such as headers and links, appear. These Style Sheets can then be applied to any Web page.
So, if you found that exciting, you have my sympathy. :)
