I've seen graphical guides for CSS and I've seen very complete descriptions of CSS elements, but this books a great combination of the two. For every styling element mentioned in this book, there is at least one diagram to help understand how it works. I found this extremely useful for floating elements. There are 9 given situations where blocks are floating in the page. For each example, a supporting diagram shows where the element is put in the code of the page and where it actually will display based on the floating attributes and what other blocks are already on the page.
