    Organizing content

    ☐ Content is organized under headings and subheadings.

    ☐ Headings and subheadings are used sequentially (e.g., Heading 2, Heading 3, Heading 4. In LibreTexts Heading 5 and Heading 6 are reserved for Textboxes and Heading 1 label the page title).


    ☐ 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 color to convey information.

    ☐ Images that are purely decorative do not have alt text descriptions. (Descriptive text is unnecessary if the image doesn’t convey contextual content information).


    ☐ The link text describes the destination of the link and does not use generic text such as “click here” or “read more.”

    ☐ If a link will open or download a file (like a PDF or Excel file), a textual reference is included in the link information (e.g., [PDF]).

    ☐ 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]).

    ☐ For citations and references, the title of the resource is hyperlinked, and the full URL is not hyperlinked.


    ☐ Tables are used to structure information and not for layout.

    ☐ 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.


    ☐ All audio content includes a transcript. The transcript includes all speech content and relevant descriptions of non-speech audio and speaker names/headings where necessary.

    ☐ Videos have captions of all speech content and relevant non-speech content that has been edited by a human for accuracy..

    ☐ All videos with contextual visuals (graphs, charts, etc.) are described audibly in the video.


    ☐ Equations written in plain text use proper symbols (i.e., −, ×, ÷).[1]

    ☐ Complex equations must be written using LaTeX and are rendered with MathJax (LaTex).

    ☐ Written equations are properly interpreted by text-to-speech tools.[2]

    Font size

    ☐ Font size is 12 point or higher for body text in Word and PDF documents.

    ☐ Font size is 9 point for footnotes or endnotes in Word and PDF documents.

    ☐ Font size can be enlarged by 200 per cent online using the readability tab or <cntl> +/- without needing to scroll side to side.

    1. For example, a hyphen (-) may look like a minus sign (−), but it will not be read out correctly by text-to-speech tools.
    2. Written equations should prioritize semantic markup over visual markup so text-to-speech tools will read out an equation in a way that makes sense to auditory learners. This applies to both equations written in LaTeX and equations written in Microsoft Word’s equation editor.
