Why Accessibility Overlays Fail And Why They Don’t Protect You From ADA Lawsuits

Written By Nichole Holzum

Short answer: Accessibility overlays do not make your website compliant. They do not prevent lawsuits. And in many cases, they create a false sense of security while real accessibility barriers remain. Several of the overlay companies have faced legal challenges in court for ADA violations themselves. 

What Is an Accessibility Overlay?

An accessibility overlay is a JavaScript-based tool that sits on top of your existing website and allows users to:

  • Change font sizes

  • Adjust contrast

  • Enable a screen reader mode

  • Modify colors or animations

Popular vendors market these tools as:

“Instant ADA compliance”

“One-click accessibility”

“Lawsuit protection”

On the surface, things look great–accommodating even. However, these claims are legally and technically misleading. And they create more barriers for those using assistive technology. 

Overlays Don’t Fix the Problems

Overlays do not change your site’s source code. That means:

  • Improper heading structure remains broken

  • Missing form labels remain missing

  • Keyboard traps remain active

  • Broken focus order remains broken

  • Screen reader navigation errors remain unfixed

Overlays attempt to mask symptoms rather than correct the underlying accessibility violations.

Real accessibility lives in:

  • Semantic HTML

  • Proper ARIA usage

  • Logical focus order

  • Accessible forms

  • Correct contrast at the CSS level

Overlays cannot reliably fix these issues after the fact.
