Visual content includes pictures, clip art, SmartArt graphics, shapes, groups, charts, embedded objects, ink, and videos.
Alt text helps people who can’t see the screen to understand what’s important in images and other visuals. Avoid using text in images as the sole method of conveying important information. If you must use an image with text in it, repeat that text in the document. In alt text, briefly describe the image and mention the existence of the text and its intent.
To determine whether hyperlink text makes sense as standalone information and whether it gives readers accurate information about the destination target, visually scan the workbook.
People who use screen readers sometimes scan a list of links. Links should convey clear and accurate information about the destination. For example, instead of linking to the text Click here, include the full title of the destination page.
Screen readers read sheet names, which provide information about what is found on the worksheet, making it easier to understand the contents of a workbook and to navigate through it.
Screen readers keep track of their location in a table by counting table cells. If a table is nested within another table or if a cell is merged or split, the screen reader loses count and can’t provide helpful information about the table after that point. Blank cells in a table could also mislead someone using a screen reader into thinking that there is nothing more in the table. Screen readers also use header information to identify rows and columns.
