Become an Accessibility BFF with your new friend Pa11y!
summary
Pa11y is an automated accessibility tester that runs Puppeteer to crawl single‑page apps, injects HTML CodeSniffer, and takes screenshots for visual debugging. It finds concrete issues like missing alt text and incorrect heading nesting on a local Angular GossipGirl rebuild, reports exact selectors and messages, and can run as a CI gatekeeper with a failure threshold. It also offers a dashboard and API for historical tracking. Reminder: about 15% of users face disabilities so fixes yield immediate UX and SEO gains.
