Using labels, names, and text alternatives consistently for content that has the same functionality

Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.1 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.1.

Applicability

All content.

This technique relates to Success Criterion 3.2.4: Consistent Identification (Sufficient, together with ).

Description

The purpose of this technique is to help users with cognitive disabilities, blindness and vision loss to understand what will happen when they interact with a function on a Web page. If there are different labels on user interface components (i.e., elements, links, JavaScript objects, etc.) that have the same function, the user will not know that they have encountered a component with the same function and will not know what to expect. This could lead to many unnecessary errors. It is also recommended that this approach to consistent labelling be applied across the Web site.

Examples

Tests

Procedure

  1. Check that each component is associated with text that identifies it (i.e., label, name, or text alternative).
  2. Check that this associated text is identical for each user interface component with the same function.

Expected Results

  • Checks #1 and #2 are true.
