80	```
81
82	## Common Fixes
83
84	### Missing Labels
85
86	```jsx
87	// Bad
88	<input type="email" placeholder="Email" />
89
90	// Good
91	<label htmlFor="email">Email Address</label>
92	<input id="email" type="email" aria-required="true" />
93	```
94
95	### Color Contrast
96
97	```css
98	/* Bad (2.8:1) */
99	color: #888;
100	background: #fff;
101
102	/* Good (4.5:1) */
103	color: #595959;
104	background: #fff;
105	```
106
107	### Keyboard Focus
108
109	```css
110	/* Ensure visible focus indicator */
111	:focus {
112	outline: 2px solid #0066CC;
113	outline-offset: 2px;
114	}
115
116	/* Don't remove outlines */
117	:focus {
118	outline: none; /* ❌ BAD */
119	}
120	```
121
122	### ARIA for Dynamic Content
123
124	```jsx
125	// Announce errors
126	<div role="alert" aria-live="assertive">
127	{error && <p>{error}</p>}
128	</div>
129
130	// Loading states
131	<button aria-busy={loading} aria-label={loading ? "Loading..." : "Submit"}>
132	Submit
133	</button>
134	```
135
136	## Best Practices
137
138	1. Semantic HTML: Use `<button>`, `<nav>`, `<main>`, not `<div onClick>`
139	2. Alt text: All images need alt (empty `alt=""` for decorative)
140	3. Form labels: Every input needs a `<label>` or `aria-label`
141	4. Color contrast: 4.5:1 for normal text, 3:1 for large (18px+)
142	5. Keyboard navigation: All interactive elements reachable by Tab
143	6. Focus indicators: Visible focus styles (don't remove outline)
144	7. ARIA carefully: HTML semantics first, ARIA as supplement
145	8. Test with real users: People with disabilities provide best feedback
