Focus indicator is visible on all interactive elements

Removing focus indicators with outline: none without a replacement makes keyboard navigation invisible. Users who cannot use a mouse — including those with motor disabilities, power users, and anyone without a pointing device — lose their only visual cue for where focus is on the page. WCAG 2.2 SC 2.4.11 (Focus Appearance) at Level AA requires focus indicators to have at least 3:1 contrast against adjacent colors. SC 2.4.7 at Level AA also requires that keyboard focus is always visible.

Replace every outline: none or Tailwind outline-none with a custom focus style. Use :focus-visible so mouse users are not affected.

/* Remove this from global styles */
*:focus { outline: none; }

/* Replace all outline removals with visible styles */
.btn:focus-visible {
  outline: 2px solid #4f46e5;
  outline-offset: 2px;
}

In Tailwind, replace outline-none with:

className="... focus-visible:ring-2 focus-visible:ring-indigo-500 focus-visible:ring-offset-2"

Search your codebase for every occurrence of outline: none, outline: 0, and the Tailwind class outline-none. Each must be paired with an explicit replacement focus style that meets 3:1 contrast against adjacent colors per WCAG 2.2 SC 2.4.11.

• ID: focus-visible

• Severity: high

• What to look for: Count all locations where outline: none, outline: 0, or outline-none (Tailwind) appear in global CSS, component styles, and utility classes. For each, verify a replacement focus style exists (:focus-visible or :focus pseudo-class with border, box-shadow, or outline with offset). Verify that focus indicators have at least 3:1 contrast ratio against adjacent colors per WCAG 2.4.11.

• Pass criteria: Count all outline-removal declarations found. 100% of outline removals are accompanied by a visible replacement focus style. Focus indicator contrast is at least 3:1 against adjacent colors. No more than 0 interactive elements may lack a visible focus indicator.

• Fail criteria: Interactive elements have outline: none or outline-none without a visible replacement focus style.

• Skip (N/A) when: Never.

• Detail on fail: "Global CSS removes outlines with *:focus { outline: none } but provides no replacement focus style" or "Button component uses outline-none without focus-visible ring"

• Remediation: Never remove focus indicators without providing a visible replacement:

  /* Before — removes focus for everyone */
  button:focus { outline: none; }
  
  /* After — custom focus style that's visible */
  button:focus-visible {
    outline: 2px solid #4f46e5;
    outline-offset: 2px;
  }
  

  In Tailwind: replace outline-none with focus-visible:ring-2 focus-visible:ring-offset-2 focus-visible:ring-blue-500.
