Web Development & Design Foundations with HTML5

Chapter 4 Visual Elements and Graphics

A key component of a compelling website is the use of interesting and appropriate graphics. This chapter introduces you to working with visual elements on web pages.

When you include images on your website, it is important to remember that not all users are able to view them. Some users may have vision problems and need assistive technology such as a screen reader application that reads the web page to them. In addition, search engines send out spiders and robots to walk the web and catalog pages for their indexes and databases; such programs do not access your images. Visitors using a mobile device may have images disabled. As a web developer, strive to create pages that are enhanced by graphical elements, but are usable without them.
