Web Development and Design Foundations with XHTML, 5th Edition

CHAPTER

This chapter introduced the use of visual elements and graphics on Web pages. As you
continue to create Web pages, refer to the guidelines and accessibility issues related to
graphics. The number one reason visitors leave Web pages is long download times.
When using images, be careful to minimize download time. Also, provide alternatives to
images (such as text links) and use the altattribute on your pages.

Visit the textbook Web site at http://www.webdevfoundations.net for examples, the
links listed in this chapter, and updated information.
