      What are accessibility overlays?
      – Accessibility overlays is a plug-in tool ‘that detects accessibility issues directly on a webpage and tries to ‘repair’ them in real-time, instead of inside of the web code. “Typically, you’ll get a snippet of JavaScript code to plug into your website, which will then try to automatically fix accessibility issues in the background as the page loads.”
      – Accessibility overlays are marketed to ‘instantly make all necessary repairs on your website and help your Web Content Accessibility Guidelines (WCAG) problems disappear.’
      Why are they bad?
      – They don’t properly solve for accessibility. And to improve digital accessibility is to actually do the work required.
      – The plug-in tool has inadequacies by applying automatic fixes to the issues detected, theirs also risks in breaking the website’s user interface.
      – Overlays don’t address your Mobile properties.
      – Overlays also inhabit no control over the speed or security of the website, which could result in being hacked.

      What is the best solution?
      – ‘To achieve WCAG is to do the work, complete an automated and manual audit of your site and address all accessibility issues you uncover at their core. Can also mean updating your content and code.’
