Accessible overlays, also known as “accessibility overlays” or “accessibility widgets,” are tools or plugins that can be added to a website, in an attempt to make it more accessible to users with disabilities. However, these overlays can actually create more accessibility problems than they solve.

One issue with accessible overlays is that they are often added as an afterthought and are not integrated into the website’s design and development process. This means that they may not be fully compatible with the website, resulting in a poor user experience for people with disabilities.

Another issue is that accessible overlays often do not conform to web accessibility standards and guidelines, such as the Web Content Accessibility Guidelines (WCAG). This means that the website may still not be fully accessible to users with disabilities, even with the overlay in place.

Additionally, accessible overlays can also create a false sense of accessibility, as they are not always effective in providing accessibility solutions for everyone. They can also create confusion for users with disabilities who may not understand the different accessibility features provided by the overlay.

Because of these issues, accessible overlays can create more problems than they solve, and it’s better to design and build an accessible website from the ground up, adhering to web accessibility standards.

Many experts in the field of web accessibility have written about the problems with using accessible overlays as a solution for making websites more accessible to users with disabilities. Here are some resources you can use to learn more:

  • The W3C Web Accessibility Initiative (WAI) has published an article on “Why Accessibility Overlays Should Be Avoided” ( which highlights some of the key issues with using overlays as a solution for accessibility.
  • The WebAIM (Web Accessibility In Mind) organization has also published an article on “Why Accessibility Widgets are Problematic” ( which explains why accessible overlays can create more problems than they solve.
  • The Accessibility Guidelines for Web Content (WCAG 2.1) does not recommend the use of overlays, as it does not guarantee that the website is accessible, and it can create confusion for users with disabilities.

Website owners should care about their site being accessible because it ensures that all users, including those with disabilities, can access and use their website. This can include users who use assistive technologies, such as screen readers, or those with cognitive or motor impairments. Making a website accessible can also improve its usability for all users, and can increase the potential audience for the site.

Additionally, there are legal requirements for accessibility in some countries, such as the Americans with Disabilities Act (ADA) in the United States, so non-compliance can result in legal consequences.

There are several examples of legal issues related to website accessibility that website owners should be aware of.

In the United States, the Americans with Disabilities Act (ADA) prohibits discrimination against individuals with disabilities in the areas of employment, transportation, public accommodations, and telecommunications. Title III of the ADA requires that “places of public accommodation” be accessible to individuals with disabilities. This has been interpreted to include websites of businesses that operate places of public accommodation, such as retail stores or hotels.

In some cases, courts have found that websites that are not accessible to individuals with disabilities are in violation of the ADA, and website owners have been held liable for damages and required to make their sites accessible.

In Canada, the Accessibility for Ontarians with Disabilities Act (AODA) applies to the public sector and private sector organizations of a certain size, and it requires them to have an accessibility policy and to make their website and web content conform to WCAG 2.0 AA standards.

In the United Kingdom, The Equality Act 2010 requires service providers to make reasonable adjustments to ensure that their services are accessible to disabled people. This includes websites and mobile applications.

Based on the potential legal ramifications, website owners should be aware of the legal requirements of the country where their website is operating and demonstrate efforts to conform to the legal requirements as they relate to accessibility guidelines.
