Ali, Sinclair Community College William Dubie, University of Massachusetts—Lowell Linda Haberaecker, Davenport University—Livonia Dana Hooper, University of Alabama Bernice Howard, St. Johns River Community College Lisa Macon, Valencia Community College Sharon Scollard, Mohawk College Luke Sui, Daytona State College John Taylor, Southeastern Technical College “The New Perspectives on HTML, CSS, and Dynamic HTML, 5th Edition text follows in the tradition of earlier editions with its hands-on, case-based approach, which has helped thousands of my students succeed in their pursuit of a career in Web Development. The new pedagogical features, especially the Visual Overviews at the start of each new session, will appeal to students with a variety of learning styles. The 4th Edition is a student favorite among text books. I predict that the 5th Edition will accomplish that which I thought was impossible: to top its predecessor in popularity. Add the fun students have working through the real-world tutorials to the deep learning that occurs as a result, and we end up with a student prepared for a high-paying industry career.” —Lisa Macon, Valencia Community College Copyright 2012 Cengage Learning.

Preface The New Perspectives Series’ critical-thinking, problem-solving approach is the ideal way to prepare students to transcend point-and-click skills and take advantage of all that HTML, CSS, and DHTML have to offer. In developing the New Perspectives Series, our goal was to create books that give students the software concepts and practical skills they need to succeed beyond the classroom. We’ve updated our proven case-based pedagogy with more practical content to make learning skills more meaningful to students. With the New Perspectives Series, students understand why they are learning what they are learning, and are fully prepared to apply their skills to real-life situations.

System Requirements This book assumes that students have an Internet connection, a text editor, and a current browser that supports HTML5 and CSS3. The following is a list of the most recent versions of the major browsers at the time this text was published: Internet Explorer 9 (public beta), Firefox 4.0.2 (public beta), Safari 5.0.2, Opera 10.6, and Google Chrome (6.04). More recent versions may have come out since the publication of this book. Students should go to the Web browser home page to download the most current version. All browsers interpret HTML and CSS code in slightly different ways. It is highly recommended that students have several different browsers installed on their systems for comparison. Students might also want to run older versions of these browsers to highlight compatibility issues. The screenshots in this book were produced using Internet Explorer 9.0 running on Windows 7 Professional (64-bit), unless otherwise noted. If students are using different browsers or operating systems, their screens will vary slightly from those shown in the book; this should not present any problems in completing the tutorials. www.cengage.com/ct/newperspectives v Copyright 2012 Cengage Learning.
