Whether you are creating a public Web site for millions to use, or a small intranet Web application, you must strive to make it usable by the widest possible audience. By making your site accessible, you make it usable by those who prefer non-traditional input and display devices. For example, many a user does not use a conventional mouse, and other users use screen readers to read the text on Web sites, rather than displaying it on a monitor. This lesson provides best practices for making your Web application accessible.

Many people are working to make technology accessible to the widest audience pos sible. One of the most prominent groups is the World Wide Web Consortium (W3C), a Web standards organization. Through the Web Accessibility Initiative, the W3C has created the Web Content Accessibility Guidelines (WCAG).

The WCAG is very thorough; this book only attempts to cover the key points as they relate to ASP.NET development. For more information about WCAG, visit http://www.w3.org/WAI/.
The United States government has also created accessibility standards in Section 508 of the Rehabilitation Act. Depending on the organization for which you are develop ing a Web application, you may be required to conform your application to these stan dards. The Section 508 guidelines are conceptually similar to the WCAG guidelines.

How ASP.NET Controls Support Accessibility
ASP.NET controls are designed to be accessible by default. For example, login con trols such as Login, ChangePassword, PasswordRecovery, and CreateUserWizard use text boxes with associated labels to help a user who uses a screen reader or who does not use a mouse. These controls also use input controls with tab index settings to make data entry without a mouse easier. Another way some ASP.NET controls support accessibility is by allowing users to skip link text. Screen readers typically read the text of links from the top to the bottom of a page, enabling users to choose a specific link. ASP.NET controls that include naviga tion links provide the SkipLinkText property, which is enabled by default and allows users to skip past the link text. The CreateUserWizard, Menu, SiteMapPath, TreeView, and Wizard controls each support skipping links. These links are not visible to users viewing the page with a traditional Web browser. For example, the following HTML source code (which has been slightly simplified) is generated by default when you add a Menu control to a Web page:
<a href="#Menu1_SkipLink"> <img alt="Skip Navigation Links" src="/WebResource.axd d=_9Q2Lm" width="0" height="0" /> </a> menu links <a id="Menu1_SkipLink"></a>
As the HTML demonstrates, a zero-pixel image file with the alt text Skip Navigation Links links to a location on the page immediately after the menu. While traditional browsers do not display the zero-pixel image, screen readers read the alt text and allow users to skip past the menu. The simplest way to follow this best practice is to use one of the ASP.NET controls that provides the SkipLinkText property. However, if you implement custom controls with navigation links, you can provide similar functionality. Though ASP.NET controls are designed to be as accessible as possible, you, as the developer, must take advantage of some features by providing text descriptions of some controls. The next sections provide more detailed information.

Improving Visual Accessibility
Many users have tools to supplement or replace a traditional monitor. These tools include screen readers, magnifiers, and high-contrast display settings. To make your application as accessible as possible using these tools, follow these guidelines:
