Standards compliance
To the best of our ability, all pages on this site:
- Partially conformant: some parts of the content do not fully conform to the WCAG 2.1 accessibility standard (not all images have alternate text).
Links
- Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target.
- There are no “
javascript:” pseudo-links. All links can be followed in any browser, even if scripting is turned off. - Most links open in a new tab.
Images
- Purely decorative graphics include null ALT attributes.
Visual design
- This site uses cascading style sheets for visual layout.
- If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
- This site uses only relative font sizes, compatible with the user-specified “text size” option in visual browsers.
