Common Mistakes to Avoid
Common Mistakes to Avoid
Removing outline without providing alternative focus indicator
Never use outline: none without adding a visible :focus-visible style. This breaks keyboard accessibility and fails WCAG 2.4.7.
Confusing outline with border
Outline does not take up space or affect layout. It can overlap adjacent elements. Use border when you need the element to reserve space for the line.
