This book is aimed at people who have built Websites before. Although IHeroturko??™ll briefly cover HTML and CSS, you should already have experience working with these technologies. Some experience with JavaScript might also be useful, but it is by no means critical: modern scripting techniques are sometimes quite different than Heroturko???old-styleHeroturko??? JavaScript.
By the time youHeroturko??™ve read the whole book, youHeroturko??™ll have a clear understanding of how to build your sites so that you can easily hook DHTML scripts into them; youHeroturko??™ll know how to work in a cross-browser and cross-platform way; lastly, you will understand the power and flexibility that can be brought to your sites through DOM enhancements.
