Canvas - Rich Content Editor Accessibility Checklist

Last Updated: 03/19/2018


Creating accessible HTML course content will help ensure all students can access your course content. This checklist covers a variety of accessibility best practices for the Rich Content Editor in Canvas.


Link Text 


  • Style all of your section headings using the “Header” styles (listed under the “Paragraph” drop-down menu). Make sure they are used in a logical hierarchical order; don't skip heading levels when creating subsections.
  • For more details, see OIT’s tutorial on Canvas Accessible Content Structure.

Color Contrast

Images & Non-Text Content

  • Add alt text to all of your images in the Insert/Edit Image dialog.
  • The text should be sufficient to explain the purpose or content of the image to someone who cannot see it. Add only as much detail to the alt-text as is needed to convey its purpose or meaning.
  • If the image is purely decorative and contains no content, you should select the Decorative Image checkbox option rather than adding alt text.

  • Tip: If you forgot to add alt text when you first inserted the image, you can re-open the Insert/Edit Image dialog box by clicking on the image and then clicking the Embed Image button in the Rich Content Editor (RCE) toolbar.

  • If you have videos in your course, consider adding captions. If you have audio files, consider adding a transcript.
