Wat is Focus Ring CSS Generator?
A focus ring is the visual indicator that shows which element is currently focused by the keyboard. WCAG 2.4.7 requires a visible focus indicator for all interactive elements. CSS :focus-visible targets keyboard focus specifically without showing a ring on mouse clicks. A good focus ring has sufficient contrast (3:1 minimum) against the background.
Snel antwoord
Generate an accessible keyboard focus ring CSS rule. Use :focus-visible to show the ring only for keyboard navigation. Ensure at least 3:1 contrast between the focus color and the background. Add a box-shadow fallback when you need rounded focus rings.
Beperkingen
- Outline does not follow border-radius in all browsers. Chrome and Safari draw outlines with square corners on rounded elements. Use box-shadow as a fallback for rounded focus indicators.
- The focus ring contrast check uses a simplified relative luminance calculation. Actual perceived contrast depends on the surrounding UI — test visually with real content.
- Some operating system high-contrast modes override author focus styles. Always test with Windows High Contrast Mode and macOS Increase Contrast settings enabled.

- If using a background color field, the tool checks the contrast ratio and warns if it falls below WCAG thresholds.
