A. Required Standards
- The current De Anza College Web standards state that all Web pages should
conform to the Priority
1 guidelines as set forth in the Web
Content Accessibility Guidelines 1.0. The district is currently in the
process of developing a more comprehensive policy based upon the Section 508
Federal Acquisition Regulations (FAR) which will be referenced here when completed.

Tech Center Training Unit Web site.
- The accessibility of each Web site is subject to the review of the college
B. Ways to Make Web Sites Accessible
- An important step in creating accessible pages is to validate your HTML.
Accessibility Tool analyzes
Web pages for accessibility.
- Make sure the HTML titles of your pages are unique. Titles are an important
navigational tool for users. Document titles are more important than people
realize. Browsers bookmark titles and search engines often look for and
- When possible, use only technologies defined in a W3C (World
Wide Web Consortium) specification and use them in an accessible manner.
When this is not possible, provide an alternative page that is accessible
and based on standards.
- All images and image map coordinates should have an ALT attribute that
alternative text that will be shown if image display is not possible or
disabled by the user. This gives the user some indication of what's missing.
- ALT attributes should be properly punctuated to allow various screen
(software for the visually impaired) to work more effectively.
- Judiciously use the appropriate amount of text in ALT attributes. ALT attributes should
sufficiently describe the image in as concise a manner as possible. If your
image includes text, the ALT attribute should reflect that text.
- ALT attributes such as "image" or "photo" are uninformative. Make your
ALT text specific and meaningful. Using transparent GIF spacers is fine,
but they need to have ALT text. For non-essential images, you can use a
blank ALT attribute; for example, ALT="" is acceptable for spacer GIFs or other
non-critical or content-devoid images.
- If you use a colored background, make sure there is high contrast between
the background and text. Avoid backgrounds with busy patterns, since these
can make text difficult to read.
- When using tables to represent data, rows and columns should be clearly
labeled and the summary attribute should be used in the table tag. This
does not apply to tables used for layout.
