(Abbreviated Level A conformance as per WCAG 2.0)
Use HTML whenever possible
- Avoid PDF, DOC, etc.
- HTML is universal, efficient and doesn't require additional software, readers, etc.
- Use PDF format when necessary but provide accessible text-based PDF's instead of image-based PDF's (see tutorial).
- Concise descriptions of images in context in ALT tags (including all image map hot spots).
- Use <ALT=””> (null alt attribute) for all unimportant design elements.
- Descriptive ALT tags are unnecessary for image-based links with link descriptions.
Use descriptive links instead of URL links (video tutorial)
- Concise descriptions of linked content are read by assistive technology instead of long, full, and oft-cryptic URL's.
- Use header tags (i.e. H1, H2, H3) for logical hierarchical order.
- H1 is reserved by Canvas for page titles so start with H2 for headings and H3 for subheadings, and so on.
Text Equivalents for all Multimedia Elements
- Transcripts and captions for all video (prerecorded and streaming).
- Transcripts for all audio.
- Use contrasting colors for page design (see tool).
- Avoid using color as a teaching element (i.e. click the green button for "yes" and the red button for "no").
Text Only Pages
- These are pages used as text equivalent substitutes for pages containing non-text elements.
- If unavoidable, they must be updated as frequently as primary pages.
