    Organizing Content

    • Content is organized under headings and subheadings
    • Headings and subheadings are used sequentially (e.g. Heading 1, heading 2, etc.)

    • Images that convey information include Alternative Text (alt-text) descriptions of the image’s content.
    • Graphs, Charts, and Maps include supporting details in the text surrounding the image.
    • Images do not rely on color to convey information.
    • Images that are purely decorative contain empty alternative text descriptions. (Descriptive text is unnecessary if the image doesn’t convey contextual content information).
    Example of image import using CK Editor.

    • Tables include row and column headers.
    • Table includes title or caption.
    • Table does not have merged or split cells.
    • Table has adequate cell padding.
    Example of accessible tables
    Tables should have clear column headers for screen readers.


    • The weblink is meaningful in context, does not use generic text such as “click here” or “read more”.
    • Weblinks do not open new windows or tabs.
    • If the weblink must open in a new window, a textual reference is included in the link information (for example, “Link Opens in a New Window”
