Provide appropriate alternative text Links to an external site.

Alternative text provides a textual alternative to non-text content in web pages. It is especially helpful for people who are blind and rely on a screen reader to have the content of the website read to them.

Provide appropriate document structure Links to an external site.

Headings, lists, and other structural elements provide meaning and structure to web pages. They can also facilitate keyboard navigation within the page.

Provide headers for data tables Links to an external site.

Tables are used online for layout and to organize data. Tables that are used to organize tabular data should have appropriate table headers (the <th> element). Data cells should be associated with their appropriate headers, making it easier for screen reader users to navigate and understand the data table.

 

Ensure links make sense out of context Links to an external site.

Every link should make sense if the link text is read by itself. Screen reader users may choose to read only the links on a web page. Certain phrases like "click here" and "more" must be avoided.

Caption and/or provide transcripts for media Links to an external site.

Videos and live audio must have captions and a transcript. With archived audio, a transcription may be sufficient.

Ensure accessibility of non-HTML content, including PDF files Links to an external site., Microsoft Word Links to an external site. documents, PowerPoint Links to an external site. presentations and Adobe Flash Links to an external site. content.

In addition to all of the other principles listed here, PDF documents and other non-HTML content must be as accessible as possible. If you cannot make it accessible, consider using HTML instead or, at the very least, provide an accessible alternative. PDF documents should also include a series of tags to make it more accessible. A tagged PDF file looks the same, but it is almost always more accessible to a person using a screen reader.

Do not rely on color alone to convey meaning Links to an external site.

The use of color can enhance comprehension, but do not use color alone to convey information. That information may not be available to a person who is colorblind and will be unavailable to screen reader users.
