Today's Web sites require streamlined code that adapts to a variety of screen resolutions, Web browsers, and user needs. CSS and XHTML are the keys to creating that, and they're the foundation upon which all modern Web sites are built. This means Web developers need a deep understanding of CSS and XHTML.

In this course, you'll take your CSS and XHTML skills to the next level and learn how to create professional-quality Web sites. You'll find out the methods the pros use to quickly build effective sites that are easy to maintain and modify. You'll discover the secrets to ensuring you keep total creative control over every aspect of a site. You'll master specific techniques for creating flexible, table-less page layouts that adapt to all Web browsers, screen resolutions, and user needs. And you'll learn how to build accessibility and search engine optimization into those page layouts.

A new section of each course starts monthly. If enrolling in a series of two or more courses, please be sure to space the start date for each course at least two months apart.

All courses run for six weeks, with a two-week grace period at the end. Two lessons are released each week for the six-week duration of the course. You do not have to be present when lessons are released. You will have access to all lessons until the course ends. However, the interactive discussion area that accompanies each lesson will automatically close two weeks after the lesson is released. As such, we strongly recommend that you complete each lesson within two weeks of its release.

The final exam will be released on the same day as the last lesson. Once the final exam has been released, you will have two weeks to complete all of your course work, including the final exam.

You'll need a simple text editor like Notepad in Windows or other Web development tool, as well as basic computer skills, and some familiarity with HTML and CSS. Internet access, e-mail, the Microsoft Internet Explorer or Mozilla Firefox Web browser, and the Adobe Flash and PDF plug-ins (two free and simple downloads you obtain at http://www.adobe.com/downloads by clicking Get Adobe Flash Player and Get Adobe Reader).

Note: Successful completion of "Introduction to CSS and XHTML" course, or prior experience with HTML and Web publishing is recommended.

“ Excellent instructor! Went above and beyond in answering students' questions and providing solutions to problems, even if they were beyond the scope of the course. ”

“ This was a fantastic course. I've taken several from this instructor and he has always been very helpful...almost going above and beyond. Thank goodness he did because I learned so much. ”

“ Alan is about the best teacher I've ever had. He's an expert in CSS and XHTML, so he can speak from experience about the best way to do things. He also writes clearly, at a level of difficulty that we students can understand. He's very patient when we ask a question or make a mistake. And he really "goes the extra mile" for his students. If you ask a question, he responds very fast, with an answer to your question and a complete code example where appropriate. Also, he'll look at CSS and XHTML that you've written outside of class, and tell you what you did right, and where you might improve. I recommend Alan highly as a teacher. ”

“ Mr. Simpson is a wonderful teacher, capable of conveying somewhat complex concepts in a manner in which we could understand. He promptly answered all of our questions via the extremely bustling discussion area. I learned a tremendous amount, and highly recommend this course! ”

“ A very good course in the actual application of CSS/XHTML - a "must" for the aspiring web developer. I would recommend Alan's course to anyone! ”
