Best Practices#
Accessibility:
✓ Always provide visible focus indicators

✓ Match focus style to brand
✓ Use consistent focus patterns
✓ Consider dark/light modes
Implementation:
✓ Test in all browsers
✓ Provide fallbacks
✓ Use outline-offset for spacing
✓ Consider animation preferences
Avoid:
✗ Removing outline without replacement
✗ Low contrast focus indicators
✗ Inconsistent focus styles
✗ Ignoring form elements
Conclusion#
Focus styling is crucial for accessibility. Use :focus-visible for keyboard-only focus indicators, ensure sufficient contrast, and provide consistent patterns across your site. Never remove focus styles without providing an equally visible alternative.
