We do our best to make our site accessible and usable by everyone--including those with physical, visual, or other impairments. To this end, several features are available to those with accessible web browsers. These features are listed below, and are courtesy of Mark Pilgrim's Dive Into Accessibility and Accessify.com.
Access keys
Most browsers support jumping to specific links by typing keys defined on the web site. On Windows, you can press ALT + an access key; on Macintosh, you can press Control + an access key.
Pages on pnhp.org follow this access key legend:
| Access Key 1 | Home page |
| Access Key 2 | Skip to main content |
| Access Key 4 | Search box |
| Access Key 9 | Feedback |
| Access Key 0 | Accessibility statement |
Naviation Aids
All archive pages have rel=previous, next, up, and home links to aid navigation in text-only browsers and screen readers. Mozilla users can also take advantage of this feature by selecting the View menu, Show/Hide, Site Navigation Bar, Show Only As Needed (or Show Always). Opera 7 has similar functionality.
Links
- 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).
- Whever 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 "
javascript:" pseudo-links. All links can be followed in any browser, even if scripting is turned off. - There are no links that open new windows without warning.
Images
- All content images used in the home page and all archives include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.
