I like examples, how things work, but not a lot of fluff... Two books permanently on my shelf for CSS and HTML are Stylin' with CSS by Charles Wyke-Smith, and Visual Quickstart Guide to HTML by Elizabeth Castro. Both books covered the basics enough to get a grasp of the big picture. Mainly if I had a question about where X goes where and what Y does, I could find an direct answer from these books usually with an example if applicable. There are probably a bunch of common front-end situations you could cover in a book would be great (AJACX search queries, the basics of responsive design (it all starts in the CSS) etc. And another suggestion - avoid using frameworks. You want your book to last, don't use some framework-du-jour, keep it vanilla and then let the reader decide what framework would better fit their work later on. If you do use frameworks - make sure the framework is listed in the title or content info so folks can decide if that would be useful for them.
