To help make Microsoft Word documents accessible, use heading styles (located in the style gallery) to add headings and subheadings to structure your content. The heading levels should follow the structure of your document's outline. Appropriate use of heading levels will help those using screen readers to interpret how the page is organized, allowing for quick navigation to different content areas.
1. Select the text you want to use as a heading.
2. Select the Home tab on the ribbon.
3. In the styles gallery, choose the appropriate heading level for the selected text.
4. If you don't see the heading level you need, click the bottom arrow in the styles gallery scrollbar to expand the gallery.
1. In the Styles group, click the small arrow to open the Styles pane.
2. At the bottom of the pane, click Options... .
