For a component that users may interact with, what is the focus requirement regarding contrast?

For interactive components, ensuring that a focus indicator is detectable at all times is crucial for accessibility. This requirement is grounded in the need for users to see when they are navigating within a digital interface, especially for those who rely on keyboard navigation or other assistive technologies. A consistent focus indicator aids users in understanding which element is currently active, allowing them to interact effectively with the interface.

The focus requirement surrounding contrast emphasizes that this indicator should maintain sufficient contrast against the background, ensuring visibility under various conditions. Continuous visibility not only assists users with visual impairments but also enhances usability for all users by providing clarity in navigation.

This focus on detectability at all times aligns with the principles of inclusive design, reinforcing that all users, regardless of their abilities, have a consistent and equitable experience when interacting with web components.
