Failure of Success Criterion 1.4.13 due to content shown on hover not being hoverable

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

Any technology that supports the display of additional content on pointer hover.

This technique relates to Success Criterion 1.4.13: Content on Hover or Focus (Failure).

Description

The objective of this failure is to describe a situation where users find it difficult or impossible to move the pointer over additional content that appears on hover. For users of screen magnification software, the new content is often not fully visible in the current magnifed section. In order to perceive it, it is therefore critical for these users to be able to move the pointer away from the trigger and over the additional content, and thereby change the position of the magnified section, without this content disappearing.

Examples

Tests

Procedure

For each area of additional content that appears on pointer hover:

  1. The pointer can be moved over the new content without the additional content disappearing.
  2. The appearance of the additional content is controlled by the user agent, not the author.

Expected Results

  • If #1 and #2 are false, then content fails the Success Criterion.
