Checking Accessibility


D2L's built in Accessibility Checker is designed to check everything on your page, including things such as:

  • Proper use of Headings. This confirms that proper placement and sequence (H1, H2, H3...) is used on the page.
  • Proper color contrast. This checks the same thing as outlined in the Color Picker Contrast Checker page, but does it for the entire page, rather than with each color selection.
  • Proper table formatting. Specifically:
    • Whether a table caption was used at the start of the table
    • Whether the row and/or column containing the table headings is properly identified
    • Whether the heading cells are using the proper tags (<th>) and scope ("col" or "row")
  • Proper image formatting: This checks to see whether the image includes a label identifying what's in the image for those with sight impairments. Note that decorative images can be labeled as decorative, which inserts an alt="" attribute to tell the screen reader to ignore it.

To use the Accessibility Checker in D2L HTML pages, do the following:
