The book teaches readers the basics of building web sites in HTML5 and CSS3. It begins by talking about different versions of HTML and CSS, and describes how modern web pages should use structure and semantics to describe their contents. There are chapters that deal with core topics including: marking up text, images, lists, tables, forms, audio and video. Each of these chapters would introduce relevant HTML5 elements. The book then goes on to introduce CSS, and teaches the reader how CSS is used to control how their pages will look / appear. Again there are individual chapters that teach the reader how to control different types of HTML elements: text, colors, lists tables and forms. There are also chapters covering page layout and design. In particular, this covers popular topics such as responsive design (sites that adapt their layout for different devices), and progressive enhancement / graceful degradation (to handle the capabilities of different devices). Throughout the section there are tips on creating more attractive designs. Wrapping up the book shows how to take advantage of the jQuery library and how users can implement powerful JavaScripts without an in-depth knowledge of the language. This features examples such as hiding and showing content, image rotators, sliding panels of text, and tabbed content. Once a beginner has read this title, it should remain useful as a reference text as they continue to develop their site / create new web sites.
