Accessibility Guidelines- Hyperlink Text – Avoid using generic, or duplicate text for hyperlinks. This is most frequently seen with the use of "click here."
- Headings – Verify order and need for headings.
- Forms – Use ARIA tags, and form labels. See Creating Accessible Forms.
- Tables – Tables should have a summary, have properly labeled header cells, association between data cells and header cells. See Data Tables Accessibility.
- Images – Images should have an appropriate "alt tag." Any text contained in the image must be placed in the alt (but, image-based text should generally be avoided). Guideline: No more than 25% of the image should be text.
- Link Behavior – Links which open in a new window should warn the user of the behavior.
- The title attribute can be used to warn the user of the link behavior.
- Alternatively, when all links following open in a new window, then a warning in the content area like, "the following links open in a new window," may be preferred. This option is less cumbersome to non-sighted users when there are many or all links on a page opening in a new window.
- PDF Accessibility – Ensure text is accessible, and documents are not scanned images of text.
