For any of you interested in learning XHTML and CSS or want to learn more on the subjects I recommend you purchase this book.
Quote from the Author for CC
The book teaches the basics of XHTML and CSS, focusing on semantic and valid XHTML 1.0 Transitional as the student strives for XHTML 1.0 Strict. It is different from other HTML books in that it is driven by a clear separation of structure (XHTML) from presentation (CSS) and provides four levels of hand-on exercises -each with less and less guidance as the student becomes more independent. Additional topics covered are design tips and best practices, basic image editing with Photoshop, and how to choose a web host.
From the Book Catalog
Web Page Design with XHTML/CSS combines the author’s "workflow learning" approach with Labyrinth’s successful instructional and graphic design approach to introduce the budding web developers to the languages used to create web pages – specifically Extensible Hypertext Markup Language (HTML) and Cascading Style Sheets (CSS). Students are introduced to the technologies that make websites work, learn best practices for naming web pages and organizing website files, work with HTML, XHTML and CSS, and put a website on the web.
