Provide text-based clues to help users perceive content

Applicable Role(s): Content Creator, Developer


Describing content in solely visual ways, such as "above," "below," or “to the left” won't convey for people that are blind, have low vision, or use the structure of the webpage to navigate. Users that have color vision deficiencies or adjust browser style sheets may also miss elements described by color or shape.

Providing textual clues along with visual descriptors makes it easier for users to find content. Additionally, layouts may change with different devices—so features to the left of content on desktop may be above content on mobile, or disappear behind a mobile menu instead of staying above main content.

Best Practices and Tips

Tell users what a feature is called and what kind of element it is. This makes it easier for users that have to navigate by voice commands to pick which content to use and activate. People using screen readers can also find the element in listings of similar elements (i.e. lists of headings, links, images, etc.).

Use a combination of descriptors like shape, size, location, orientation along with with color/text. Don't use color alone to convey information on a page.
