Top 3 Canvas Accessibility Errors

Applying accessibility principles to Canvas is easy to implement but can be challenging to go back and fix your old content. The important detail is to start applying accessibility today, and slowly work on any legacy content. After reviewing and editing hundreds of courses, I have thrown together the top 3 accessibility errors within Canvas.

Error 1

Using tables to organize content on a page.

Tables should only be used to display data. When you use tables to organize the visual display of information on your page, you are potentially adding unnecessary barriers to the information. Navigating tables is a complicated process that requires precision when using Assistive Technology or the keyboard. Tables should compare, contrast, and be specific. When a user navigates a table with a screen reader, they need to know where they are in the table and this includes applying table header cells where appropriate.

Error 2

Using vague Links

Avoid using links that use these phrases:

They are confusing to a user using a screenreader, and they do not help students navigate any content. Using detailed links will help your students more accurately follow along with your content. Focus on using descriptive links:

Error 3

If you are creating content for your course and use videos, those videos need to be captioned. Posting a video in your course? Caption it. Found a video on the internet? Caption it. The best resource I have found for finding captioned community videos is from a site called is a site that allows users to upload community to captions to almost any Youtube video in a variety of different languages.

Caption any video that is in your course or referenced by your course. Captions help all people, not just those who need them.
