About Accessibility & Responsive Checker
Accessibility & Responsive Checker is an all-in-one developer tool designed to audit web pages for accessibility (WCAG) compliance and mobile responsiveness in a single click.
Unlike standard checkers that only look at the desktop view, this extension performs a Dual-Pass Analysis:
Desktop Analysis: Scans the current view for structural and accessibility issues.
Mobile Simulation: Automatically attaches the debugger to simulate a mobile viewport (iPhone X dimensions), detecting layout breakages that only appear on smaller screens.
Whether you are a Developer, QA Tester, or Designer, this tool helps you deliver higher-quality, inclusive web experiences.
🔍 Key Features
1. Advanced Accessibility Testing (Powered by axe-core)
Detects WCAG 2.1/2.2 A and AA violations.
Identifies low contrast text, missing ARIA labels, and incorrect roles.
Flags "ghost" interactive elements (buttons without tabindex).
Checks for focusable elements hidden from screen readers (aria-hidden="true").
2. Deep Responsive Design Analysis
Horizontal Overflow Detection: Finds elements causing unwanted horizontal scrolling on mobile.
Touch Target Validator: Checks interactive elements against modern usability standards:
Critical: Elements smaller than 24px (impossible to tap).
Warning: Elements smaller than 44px (hard to tap).
Font Legibility: flags text smaller than 11px.
Responsive Tables & Media: Identifies tables, images, or videos that break the layout without scroll wrappers.
3. Mobile UX Enhancements
Input Field Analysis: Suggests specific input types (e.g., email, tel, numeric) instead of generic text inputs to trigger the correct mobile keyboard.
Viewport Configuration: Checks for missing meta tags or user-zoom restrictions (user-scalable=no).
4. Detailed Reporting
View a clean, categorized summary of all issues directly in the popup.
One-Click Copy: Generate a full text report (including HTML snippets and selectors) to paste into tickets (Jira, Trello, GitHub) or emails.
