What does the Success Criterion 1.4.13 focus on?

Success Criterion 1.4.13 specifically addresses the need for content that is triggered by hover or focus to also be accessible to users who may not use a mouse. This criterion ensures that any important functionality or information that appears when an element is hovered over or focused upon is also available through other means, such as keyboard interactions.

The intent is to provide all users, particularly those who rely on keyboard navigation or assistive technologies, with the same access to the content and functionalities. This aligns with the broader goal of web accessibility, which is to create an inclusive experience for all users, regardless of their abilities or the devices they use.

In contrast, color contrast ratios focus on visual clarity for text and background combinations, accessible text resizing deals with user flexibility in changing text sizes without losing content, and audio description availability relates to providing additional descriptive audio for audiovisual content. While these aspects are crucial for overall accessibility, they are not the focus of Success Criterion 1.4.13.
