CSS
I think I finally have a good, basic understanding of CSS, and I owe it to this book. I looked at the book before, but it seemed gimmicky in its approach and I dismissed it. It turns out that the approach is based on sound learning principles and I found it to be a great way to learn CSS. I spent a Saturday and Sunday working through the entire book.
I have since looked at several other books in the Head First series.
Now that I better understand CSS, I should rework the templates I'm using for these journal pages -- but I'm too lazy.
