Common NVDA Issues & How to Fix Them

1. NVDA Doesn't Read Content Properly

Issue: NVDA skips content or reads it incorrectly.

Fix: Check your HTML structure. Use semantic elements (headings, paragraphs, lists). Avoid using display:none or visibility:hidden on important content.

2. Images Without Alt Text

Issue: NVDA says "image" without description.

Fix: Add descriptive alt text to all images: <img src="..." alt="Description">

3. Unlabeled Form Fields

Issue: NVDA can't announce form field purposes.

Fix: Use <label> for every form field: <label for="email">Email</label>

4. Custom Widgets Not Announced

Issue: Custom widgets (tabs, modals, sliders) aren't announced.

Fix: Add ARIA roles and attributes: role="tablist", role="tab", aria-label

5. Focus Order Issues

Issue: Tab order jumps around incorrectly.

Fix: Ensure your HTML source order matches visual order. Avoid positive tabindex values.
