- Accessibility statement
- The home page, projects page, statistics page, and all archives back to February 1, 2002 are Bobby A approved, complying with all priority 1 guidelines of the W3 Web Content Accessibility Guidelines.
- The home page, projects page, and all archives back to February 1, 2002 are Section 508 approved, complying with all guidelines of the U.S. Federal Government Section 508 Guidelines.
- The home page, projects page, and all archives validate as HTML 4 Strict.
- The home page, projects page, and all archives use structured semantic markup. For example, on pages with more than one day’s posts, H2 tags are used for dates, H3 tags for individual post titles. JAWS users can skip to the next day using ALT+INSERT+2, or the next post with ALT+INSERT+3.
- All pages on this site include a consistent set of global navigation links.
- All pages other than the home page have a “breadcrumb” trail of links leading up to the home page.
- All pages on this site include a search box (access key 4).
- Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
- Wherever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
- Link text is never duplicated; two links with the same link text always point to the same address.
- There are no “
- There are no links that open new windows without warning.
- All content images used on this site include descriptive ALT attributes. Purely decorative graphics include empty ALT attributes.
This site and all its archives use cascading style sheets for visual layout.
- Internet Explorer has a limited text resizing feature (“View” menu, “Text Size”), but it only works with relative font sizes. A special stylesheet that uses relative font sizes is automatically served to visitors using Internet Explorer.
- If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.

Accessibility books I recommend
- Joe Clark: Building Accessible Websites. I tech-edited this book; it’s excellent. Comprehensive but not overwhelming.
- Jim Thatcher and others: Constructing Accessible Web Sites. Less comprehensive than Joe’s book, but goes into greater depth in the topics it covers. Gives screenshots of how various screen readers and alternative browsers interpret various tags and markup. Also has an amazing chapter on the current state of legal accessibility requirements.
- Dive Into Accessibility, my free online book on web accessibility techniques. You can read it while you wait for the other two to be delivered.
