Tab Order / Focus Sequence Visualizer
The keyboard tab sequence is invisible — you can't see the order screen-reader and
keyboard users actually follow. This tool maps the journey with numbered badges, arrow
connectors, skip-link validation, and positive-tabindex warnings.

Introduction
Keyboard and screen-reader users navigate by pressing Tab. If the sequence jumps around the page, the experience breaks. This tool makes the sequence visible so you can fix it before users hit it.
How it works
- Renders your HTML in an isolated Shadow DOM so styles can't leak.
- Computes the tab order from
tabindexand DOM position. - Draws numbered badges and SVG arrows over each focusable element.
- Validates skip-link targets and flags positive
tabindex. - "Walk tab order" steps through the sequence with a highlight.
Privacy
All rendering and measurement is local. No upload, no account, no API key.
Limitations
- Does not traverse Shadow DOM boundaries inside your pasted snippet.
- Focusability heuristics follow standard selectors; exotic cases may vary.
FAQ
Why is positive tabindex bad?
It overrides the natural reading order and is fragile to maintain. Reorder the DOM instead.
Is my markup uploaded?
No. Everything runs locally in a sandboxed Shadow DOM.
