The guidelines below apply this concept to web page design. Following them will ensure that your Web pages are robust, standard, and accessible to the fullest possible range of users. As you build your web pages keep in mind that your audience is diverse. Not all web page visitors are using the standard graphical browsers. They may be using adaptive technologies such as screen readers or text-based browsers, have their browser graphics turned off, or may not be able to use, or have access to a mouse or keyboard.
Some users also have physical or cognitive disabilities that impact their use of a Web page.
Universal Design not only ensures that your information will be accessible to people with various types of disabilities, but also to those using old, alternate, or emerging technologies. The principles below will satisfy minimal accessibility standards for your Web page. We encourage you, however, to go beyond the minimum in making your Web page universally accessible.
