Last Edited September 26, 2023 by Garenne Bigby in Accessibility Testing

In today's digital age, access to information and services is critical for everyone, including those with disabilities. Accessibility overlays aim to provide a more inclusive online experience by making websites accessible to people with disabilities. In this article, we will look at what accessibility overlays are, how they work, and their benefits and limitations. So, let's dive in and learn more about this critical topic.

Accessibility OverlaysWhat is an Accessibility overlay?

Accessibility overlays are software solutions designed to help website owners make their sites more accessible to users with disabilities. These overlays work by adding a layer of code to a website that modifies how it looks or behaves, making it easier for disabled users to access and navigate.

Some typical features of accessibility overlays include changing font sizes, adjusting color contrast, and providing alternative text for images. These overlays can also provide keyboard navigation options for users without a mouse and audio descriptions for video content.

While accessibility overlays can be a quick and easy way to improve website accessibility, they come with several drawbacks. These include potential false positives and negatives, high costs, and legal compliance issues.

Ultimately, the decision to use accessibility overlays will depend on some factors, including the specific needs of the website and its users, the budget and resources available, and the desire to comply with legal accessibility requirements. It is essential for website owners to carefully weigh the pros and cons before implementing any accessibility solution and to seek expert advice if necessary.

The Pros and Cons

As businesses rely more on online presence, accessibility has become a significant concern for many website owners. One solution that has gained popularity is the use of accessibility overlays. But are these overlays the best solution for making websites accessible to all users? We will explore the pros and cons of accessibility overlays, helping you make an informed decision when making your website accessible.

First, let's discuss the pros of accessibility overlays. One of the main advantages of using an overlay is that it can be implemented quickly and easily. This makes it an attractive option for businesses looking for a quick fix to their accessibility issues. Additionally, overlays can help to improve the user experience for people with disabilities by providing alternative ways to navigate the website and access its content.

However, there are also many cons to using accessibility overlays. One of the main issues is that they can make things worse for users with disabilities. This is because overlays often rely on automated tools to identify and fix accessibility issues, which can lead to false positives and false negatives. For example, an overlay might identify a text link as an image, preventing users with visual impairments from accessing the link.

Another issue with accessibility overlays is that they can be expensive to implement. Many overlays require a subscription or ongoing payments, which can add up over time. Additionally, overlays can be challenging to customize and may not work well with certain website layouts or designs.

Finally, there is the issue of legal compliance. While accessibility overlays may provide a quick fix for websites, they may not be sufficient for meeting legal requirements for accessibility. If a website is found to be non-compliant, it can face legal action and fines, which can be much more costly than implementing proper accessibility measures from the start.

While accessibility overlays may seem like an attractive solution for making websites accessible, they have many drawbacks that should be carefully considered before implementation. Businesses should weigh the pros and cons and consider other options, such as manual accessibility testing, before deciding on the best approach for their website. Ultimately, the goal should be to ensure that all users can access and use the website, regardless of their abilities.

Here are the Top 5 reasons not to use accessibility overlays:

  1. They may not be fully compliant with accessibility standards: While accessibility overlays claim to make your website compliant with accessibility standards, they may not be able to meet all the requirements. This means that your website may still be inaccessible to some users, which defeats the purpose of using an overlay.
  2. They can create more accessibility issues: Accessibility overlays can sometimes create more accessibility issues than they solve. For example, they may add extra code to your website, which can slow the loading speed and make it difficult for some users to navigate.
  3. They may not work for all users: Accessibility overlays are designed to help users with disabilities, but they may not work for everyone. Some users may have specific needs that the overlay cannot address, such as those who use screen readers or have cognitive disabilities.
  4. They can be expensive: Many accessibility overlays require a subscription or licensing fee, which can be costly for small businesses or non-profits. This cost may not be sustainable in the long term, especially if you need to update or upgrade the overlay regularly.
  5. They may not be future-proof: Accessibility overlays are a band-aid solution that may not be sustainable in the long term. As technology and accessibility standards continue to evolve, an overlay may become outdated and ineffective, leading to the need for a new solution.

While accessibility overlays may seem like a quick fix, they may not be the best option for making your website accessible. It's essential to research and consider all options before deciding and prioritizing a solution that meets all accessibility standards and works for all users.

Can using accessibility overlays cause lawsuits?

There is potential for using accessibility overlays to lead to lawsuits. It's vital to ensure that websites and applications are fully accessible to all users, including those with disabilities, and relying solely on overlays may not be sufficient. It's better to focus on implementing accessible design and development practices from the beginning to avoid any legal issues.

While accessibility overlays can provide some level of accessibility, they are not a comprehensive solution and may not meet all of the legal requirements of the ADA. This means that your website or application may still risk being sued for not being fully accessible.

It is important to note that there have been several recent lawsuits related to digital accessibility, and these cases are likely to continue. In some cases, companies have been forced to pay significant fines or settlements to plaintiffs who could not access their digital content due to accessibility barriers.

UsableNet's 2022 ADA Digital Accessibility Lawsuit report highlights the continued increase in the number of lawsuits related to digital accessibility in recent years. Companies that fail to ensure their digital content is accessible to all users may face significant fines or settlements. The report recommends implementing accessible design and development practices from the beginning to avoid legal issues and ensure full accessibility. The use of accessibility overlays may not meet all legal requirements of the ADA and may leave websites or applications at risk of being sued.

To avoid legal issues and ensure that your website or application is fully accessible to all users, it is recommended that you focus on implementing accessible design and development practices from the beginning. This includes ensuring that all content is appropriately labeled and structured for assistive technologies, providing alternative text for images and other non-text content, and using color contrast and other design elements to make content more accessible.

Moving away from overlays

As the importance of web accessibility continues to grow, many website owners are looking for ways to make their sites more user-friendly for people with disabilities. However, some are turning to accessibility overlays as a quick and easy solution without fully understanding the potential drawbacks.

One major issue with accessibility overlays is that they can create a false sense of compliance. While they may improve certain aspects of accessibility, they cannot guarantee full compliance with accessibility guidelines. This is because overlays only address the surface-level issues of a website's accessibility without addressing the underlying code and design.

Another issue with accessibility overlays is that they can create a confusing and inconsistent user experience. Users with disabilities may encounter an overlay that modifies the website's design in a way that conflicts with their assistive technology or personal preferences. This can make it difficult for them to navigate the site and access the necessary information.

Moving away from accessibility overlays requires a shift in mindset from website owners. Rather than seeking a quick fix, they must prioritize building accessibility into their website design from the ground up. This means following accessibility guidelines, testing with assistive technology, and involving people with disabilities in the design process.

Ultimately, the goal of web accessibility is to create a more inclusive online experience for all users. While accessibility overlays may seem like a quick and easy solution, they often fall short in providing a truly accessible experience. By prioritizing accessibility in website design, website owners can create a more welcoming and inclusive online environment for everyone.
