原文外掛簡介
MSACAlab Accessibility Checker scans your pages with axe-core, the open-source accessibility testing engine, and shows every issue it finds grouped by WCAG criterion, page and severity, with a plain-language explanation of how to fix it.
Full audit of your pages, run from your WordPress admin
12 quick fixes with one-click undo: a skip link, keyboard focus outline, page language, mobile zoom, search and comment field labels, missing page titles, titles for embedded videos and maps, hidden empty headings and paragraphs, natural keyboard order, no clashing shortcut keys, and respect for “reduce motion” settings
Alt text screen: every image missing alt text in one list. Type a description (or mark it decorative) and save: MSACAlab Accessibility Checker adds it to the Media Library and to the pages where the image is already used. Undo is one click, and the alt text stays even if you remove MSACAlab Accessibility Checker.
Fixed and verified: after you turn a fix on, MSACAlab Accessibility Checker re-checks the affected pages and shows whether the problems are gone
Visual report with a score gauge and charts by severity, WCAG principle and type of fix
A “?” next to every problem explains in plain language why it matters, who it affects and how to fix it
Before & after: compare any two audits to see what you fixed, what remains and what is new
Download any report or comparison as a polished PDF to share with your team or clients
Checks each page at desktop and phone width, and lists anything the automated checks can’t decide on as “Needs a human check”
Three layers of automated checks: axe-core, selected IBM Equal Access rules and MSACAlab Accessibility Checker’s own checks for things like vague link text, placeholder-only fields and tables without headers
Works with popular caching and optimization plugins: caches are cleared when you change a fix, and the fixes script is never delayed
Manual checklist of 32 checks for what software can’t judge, with step-by-step instructions
Checks inside the block editor: every time you save, MSACAlab Accessibility Checker checks the post’s content and explains any problems in the sidebar and before publishing
“Show on page”: see each problem outlined on your live page, with an explanation and next/previous navigation
Dismiss issues that aren’t real problems or that you accept for now, with a reason and note. Dismissals carry over to future audits and can be restored at any time.
Accessibility statement generator: a live statement page that updates itself with your latest audit, following W3C guidance
MSACAlab Accessibility Checker does not inject an “overlay” script into your site, and it never sends your content to an outside service.
Important: Automated tools find only part of all accessibility issues. MSACAlab Accessibility Checker reports automated scan results plus the manual checks you record. It does not certify that your site conforms to WCAG.
