Does the book cover tips on how to write CSS which works across multiple browsers?
Absolutely. In fact, I wrote the book because I was having the same problem!
I have done all the cross-browser research for you. I spent months researching each CSS property and each XHTML element in each major browser and tested each for compatibility. This was a huge undertaking as you can imagine. I then eliminated all the inconsistent, unsupported, or partially supported properties. I then created patterns for each conceivable task you need to do in coding a web page. I thoroughly tested each pattern in all major browsers.
You can use my patterns with confidence that they work in all major browsers. In addition, my patterns follow best practices. They are valid, accessible, reusable, and can be combined with other patterns to create any design you can imagine.
By using the design patterns in my book, you will dramatically improve your productivity because your code will work predictably in all major browsers including Internet Explorer 6 & 7, Firefox (all versions), Opera 9, and Safari 2.
