Checklist for Accessibility

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 must be attached to headings and subheadings.  Always begin with h2.
  (e.g. h2, is used before h3)

Images

• Images that convey information have alternative text (alt text) descriptions of the image’s content or function.
• Graphs, charts, and maps  contain alt text to make the information contained in the graphic accessible to screen readers.
• Do not rely solely on colour to convey information.
• Images that are purely decorative do not require alt-tag descriptions. (Descriptive text is unnecessary if the image doesn’t convey contextual content information).

Lists

• Use the builtin tools to create lists.
  • Bulleted lists
  • Numbered lists

Links

• All links are connected to meaningful text. Generic text such as “click here” or “read more.” are not used.
• 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

• 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.
