Screen Reader Preview
Preview how your HTML will be announced by screen readers — see the accessible name, role, and reading order for each element
No announceable elements found.
This is a simplified preview of how NVDA / JAWS / VoiceOver would announce your HTML. It resolves the accessible name (aria-labelledby → aria-label → <label> → text content → alt → title → placeholder), computes implicit roles, and flags common issues. Real screen readers may differ slightly by version and browser.
