SpotCheck: Accessibility Toolkit por xirclebox

A Chrome DevTools collection of tests that allow you to spot-check common accessibility issues directly in the browser. Each one links to its related WCAG 2.2 success criteria.

Available tools:
• Landmark Visualizer
Outlines every ARIA and HTML landmark region and flags ones missing an accessible name or duplicated.

• Link Accessibility Auditor
Checks every link for a real accessible name and flags generic text like “click here”.

• Heading Validator
Walks the heading outline in document order and flags any level that skips ahead.

• List Identifier
Flags empty lists, malformed markup, and list items that aren’t inside a list at all.

• Tab Order Visualizer
Numbers every focusable element in tab order and flags positive tabindex values.

• Text Contrast Checker
Measures text contrast against its effective background and flags anything below WCAG AA minimum.

• Alt Text Checker
Checks every image for alt text and flags the ones missing it or marked incorrectly.

• Input Label Checker
Outlines every input, select, and textarea on the page, then labels each one with how it gets its accessible name.

• Target Size Checker
Run this on any page to measure every clickable target, flag the ones under 24 by 24 CSS pixels, and show which ones clear the 44 by 44 enhanced threshold.
