Checklist for Accessibility

Use this checklist to check the Accessibility as you create or modify an Open Textbook.[1]

Organizing Content

  • Header 1 tag (h1) is only used once for the chapter title. This header tag is applied automatically in Pressbooks.
  • Chapter content is organized under headings and subheadings.
  • Hierarchical tag names attached to headings and subheadings beginning with h2. (e.g. h2, is used before h3)


  • Images that convey information include alternative text (alt text) descriptions of the image’s content or function.
  • Graphs, charts, and maps also include contextual or supporting details in the text surrounding the image.
  • Images do not rely on colour to convey information.
  • Images that are purely decorative do not have alt-tag descriptions. (Descriptive text is unnecessary if the image doesn’t convey contextual content information).


  • Bulleted lists created using Bullet list icon.
  • Numbered lists created using Numbered list icon.


  • The link is meaningful in context and does not use generic text such as “click here” or “read more.”
  • Links do not open in new windows or tabs.
  • If a link must open in a new window or tab, a textual reference is included in the link information (e.g., [NewTab]).


  • Tables include row and column headers.
  • Row and column headers have the correct scope assigned.
  • Tables include a caption.
  • Tables avoid merged or split cells.
  • Tables have adequate cell padding.


A transcript is available for each multimedia resource including relevant non-speech content. Transcript includes:

  • speaker’s name
  • all speech content
  • relevant descriptions of speech
  • descriptions of relevant non-speech audio
  • headings and subheadings
  • Captions of all speech content and relevant non-speech content are included in the multimedia resource; this includes the audio synchronized with a video presentation.
  • Audio descriptions of contextual visuals (e.g., graphs, charts) are included in the multimedia resource.


  • Formulas have been created using MathML.
  • Formulas are images with alternative text descriptions if MathML is not an option.

Font size

  • Font size is 12 point or higher for body text.
  • Font size is 9 point for footnotes or endnotes.
  • Font size can be zoomed to 200%.
