When creating headings use a logical and consistent structure, begin with Heading Level 1, and don’t skip levels. You can use the default styles, or you can modify them to change your design. In Word, we use the Styles feature to add headings. Headings within a document provide hierarchical information to the screen reader about the way the document is structured: Does the document have a title? Are there topics and subtopics? If you have an existing Word document and would like to find out how accessible it is, use Word’s built-in Accessibility Checker.
This semantic information should be included in materials in ways that are accessible to users with visual disabilities. When we look at a document on our computer screen, much meaning is derived from structural cues we get from the layout and appearance of the document.
