![web accessibility overlays](https://blog.usablenet.com/hubfs/web-accessibility-overlays.jpg)

*Originally written on July 18, 2019. Content was updated in September 2023. *

In the last couple of years a range of new vendors  have started promoting solutions that claim to provide a silver bullet to web accessibility challenges. They are almost all implemented as buttons or overlays that claim to bring the site into conformance with WCAG 2.0 or 2.1 AA.  The truth is they fail in four fundamental areas. 

1. **Overlays only fix the easy stuff, leaving big accessibility gaps.** 
2. **Overlays override the user's existing assistive technology.**
3. **Overlays lack WCAG conformance certainty**
4. **Overlays do not support mobile web users** 

There are many new vendors offering similar overlay solutions  because they are technically easy-to-do and cheap-to-provide but they fail to deliver true web accessibility to all. They are feeding off the [surge of ADA-based Web accessibility](https://info.usablenet.com/ada-website-compliance-lawsuit-tracker)[law](https://blog.usablenet.com/2018-ada-web-accessibility-lawsuit-recap-report)[suits](https://blog.usablenet.com/2018-ada-web-accessibility-lawsuit-recap-report) that many  companies searching for quick solutions to the very complex issue of accessibility.  

The truth is that for companies with existing complex websites, [retail](https://blog.usablenet.com/retail-industry-becomes-top-target-for-ada-lawsuits-blog), [restaurants](https://info.usablenet.com/2019-ada-web-accessibility-lawsuit-recap-report), travel, banking and healthcare, [web accessibility](https://info.usablenet.com/web-accessibility-your-roadmap) is hard work. These solutions fail in three fundamental areas which I dive into below.  If you did not include accessibility at the start of a website build and want a solution that is usable by all and fully conforms to WCAG,  someone will have to do the hard work of updating all your code (HTML, JavaScript and CSS) and design.  

## Web Accessibility Overlays Cut Corners  

I want to be clear that these vendors do some of the work. But what they fix is easy stuff to spot and the easy stuff to fix (and maybe your own team should be doing it anyway).  After these fixes, they promise that their overlay technology can  address and fix the rest of the accessibility issues.  

Overlay-based solutions can work for simple, informational websites. But for businesses with visitor interactions  like pop-ups for product size and color selection, pop-ups to selecting seats or rooms; calendars for  delivery dates or times, account management, etc; these solutions cannot  deliver accessibility for all users. 

## Four reasons why web accessibility overlays fall short

Below I have highlighted the three biggest flaws in these solutions for modern websites. I also want to explain what they do and how they do it, so you can compare approaches. 

## 1. Overlays only Fix the easy stuff, leaving big Web accessibility gaps 

Here is how they generally work: you add a line of code to your website that calls the vendors' server to load a set of fixes they have  prepared.  It also includes an icon on your page which opens an overlay (typically they will use a little blue man which is the symbol for accessibility). The fixes loaded are only for attributes and tags on elements. This means they do not address the design of the page or the functionality.  The visual display of the web page does not change. 

[![See our full guide on web accessibility. >>](https://no-cache.hubspot.com/cta/default/3280432/485cb1cc-ad69-472b-b817-59cb57129c9d.png)](https://cta-redirect.hubspot.com/cta/redirect/3280432/485cb1cc-ad69-472b-b817-59cb57129c9d)

Element attributes such as alt tags, labels, header etc. are important for accessibility.  They are also the items that most automated accessibility testing tools, such as WAVE will find. This makes it easy for an overlay vendor to quickly demonstrate with automated tools that some of the accessibility issues have been resolved.  

Sounds good so far, right? There is a catch. The fixes added in  this process  represent [only 20% of the accessibility](https://blog.usablenet.com/automated-wcag-testing-is-not-enough-for-web-accessibility-ada-compliance)[areas](https://info.usablenet.com/c-automated-accessibility-testing) that need to be reviewed and fixed.  

Updating attributes  **cannot  address** more significant barriers. Some vendors may claim, "but we can use ARIA tags to fix complex interactions".  That can only be true if that interaction was built with ARIA in mind. However, most  existing scripting on sites did not consider accessibility when coded and how ARIA could be used. Practically speaking, those interactions need to be re-coded. That's the hard stuff.  

How do overlay vendors solve for the 80% of accessibility challenges they can’t fix by updating attributes? By pointing to their overlay technology to solve these bigger issues. They will have cool sounding features such as; text-to-speech, texted based navigation, color contrast tools, and text resizing, that look great in a demo and seem to add value.  So, what is the problem? In reality, these features offer little or no value to current assistive technology users because. . .

## **2. Overlays override the user's existing assistive technology **

This is the biggest weakness. People with disabilities who require assistive technology to use and navigate websites already have preferred assistive technology that they use every day. They have invested their time to learn how to use it and are likely most comfortable using their own devices to navigate the web. Their devices are set up to do the things they need such as, text-to-speech, zoom, color contrast, etc. An overlay attempts to replace the functionality of these devices. 

To use the "text-to-speech" feature in an overlay, the person requiring the assistive technology must turn off their own, preferred screen-reader and rely solely on the overlay. 

Joe DiNero who heads the UsableNet's User Testing group is a long-time screen reader user and a teacher at  the Helen Keller Institute in New York. He explains,

"Using the overlay screen reader instead of my regular screen reader locks me into a small set of features such as arrow, tab and maybe heading navigation. When I use my screen reader on a regular site that has been properly coded or fixed for accessibility, I can access any form control on the screen (buttons, edit fields, aria controls, etc.) and I have the ability to pull up a list of links on the page. Moving to the overlay removes all powerful and useful features from me." 

So, if an overlay-solution promises to fix 80% of the accessibility items that could not be fixed when the vendor updated attributes, then this value is likely lost for the average screen-reader user, the same customer you are trying to serve with your accessibility updates. 

## **3. Overlays lack WCAG  conformance certainty**  

All major accessibility laws and policies around the world, as well as past DOJ settlements, ADA lawsuits and resulting settlements reference the WCAG 2.0 AA as the  prevailing minimal standard. That could extend to the new WCAG 2.1 soon, but will take time for laws and policies to catch up.

The WCAG is clear on conformance. Every page’s code of a web site has to pass a set of Success Criteria. There are 37 in WCAG 2.0 AA and [WCAG 2.1](https://blog.usablenet.com/new-web-content-accessibility-guidelines-wcag-2.1-what-when-how) adds even more.

The WCAG does not  reference accessibility overlays as a means of conforming because  the only true way a person using a screen reader or other assistive technology can have full and equal access to your website is by providing them an experience where the design and code has been developed to WCAG standards. This ensures that they can  continue to use their chosen technology.

## **4. Overlays **do not support Mobile Web users**** 

The final item and really a huge blow to blind or other users that rely on mobile devices now more than desktop is the lack of support for mobile wed.

The mobile device is now the most important device in a blind users life, using it for all aspects of digital connection. When web sites use overlays they remove any benefit they may have for the most important channel in digital today. 

### **But all these solutions  promote that they are ADA compliant. How can they say that? ** 

The ADA does not define a standard for website accessibility, which is one of the main reasons there are so many lawsuits. Some companies may hope that adding an overlay is enough to avoid a lawsuit. But it may not be, and more importantly is it enough for you to not offer a fully inclusive digital experience?”

### **How can UsableNet help?** 

If you want to ensure access to all and avoid lawsuits, you need to ensure all your code is updated to WCAG standards.

They are feeding off the <A href=\"/2018-ada-web-accessibility-lawsuit-recap-report\" rel=\" noopener\">surge of ADA-based Web accessibility </A></SPAN><A href=\"/2018-ada-web-accessibility-lawsuit-recap-report\" rel=\" noopener\"><SPAN data-contrast=\"auto\">law</SPAN></A><SPAN data-contrast=\"auto\"><A href=\"/2018-ada-web-accessibility-lawsuit-recap-report\" rel=\" noopener\">suits</A> that </SPAN><SPAN data-contrast=\"auto\">many</SPAN><SPAN data-contrast=\"auto\">  companies searching for quick solutions to the very complex issue of accessibility. </SPAN><SPAN data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\"> </SPAN></P>\n<P><SPAN data-contrast=\"auto\">The truth is that for companies with existing </SPAN><SPAN data-contrast=\"auto\">complex </SPAN><SPAN data-contrast=\"auto\">web</SPAN><SPAN data-contrast=\"auto\">sites, <A href=\"/retail-industry-becomes-top-target-for-ada-lawsuits-blog\" rel=\" noopener\">retail</A>, <A href=\"/ada-restaurant-website-surfing-suits-on-the-rise\" rel=\" noopener\">restaurants</A>, travel, banking and healthcare, web accessibility is hard work. These solutions fail in three fundamental areas which I dive into below.  If you did not </SPAN><SPAN data-contrast=\"auto\">include</SPAN><SPAN data-contrast=\"auto\"> accessibility at the start of a website build and want a solution</SPAN><SPAN data-contrast=\"auto\"> that is usable by all and fully conforms to WCAG</SPAN><SPAN data-contrast=\"auto\">,  someone will have to do the hard work of updating all your code (</SPAN><SPAN data-contrast=\"auto\">HTML</SPAN><SPAN data-contrast=\"auto\">, </SPAN><SPAN data-contrast=\"auto\">JavaScript</SPAN><SPAN data-contrast=\"auto\"> and CSS) </SPAN><SPAN data-contrast=\"auto\">and design</SPAN><SPAN data-contrast=\"auto\">. </SPAN><SPAN data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\"> </SPAN></P>\n<H1><STRONG><SPAN data-contrast=\"auto\">So what corners are these new overlay companies cutting? </SPAN></STRONG><SPAN data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\"> </SPAN></H1>\n<P><SPAN data-contrast=\"auto\">I want to be clear that these vendors do some of the work. But </SPAN><SPAN data-contrast=\"auto\">what they fix</SPAN><SPAN data-contrast=\"auto\"> is</SPAN><SPAN data-contrast=\"auto\"> easy stuff to spot and the easy stuff to fix (and maybe you</SPAN><SPAN data-contrast=\"auto\">r own team</SPAN><SPAN data-contrast=\"auto\"> should be doing </SPAN><SPAN data-contrast=\"auto\">it </SPAN><SPAN data-contrast=\"auto\">anyway)</SPAN><SPAN data-contrast=\"auto\">.  After these fixes, they </SPAN><SPAN data-contrast=\"auto\">promise that their overlay technology can </SPAN><SPAN data-contrast=\"auto\"> address and fix the rest of the accessibility issues. </SPAN><SPAN data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\"> </SPAN></P>\n<P><SPAN data-contrast=\"auto\">Overlay-</SPAN><SPAN data-contrast=\"auto\">based solutions</SPAN><SPAN data-contrast=\"auto\"> </SPAN><SPAN data-contrast=\"auto\">can</SPAN><SPAN data-contrast=\"auto\"> </SPAN><SPAN data-contrast=\"auto\">work for simple, informational website</SPAN><SPAN data-contrast=\"auto\">s.

I </SPAN><SPAN data-contrast=\"auto\">also </SPAN><SPAN data-contrast=\"auto\">want </SPAN><SPAN data-contrast=\"auto\">to explain what they do and how they do </SPAN><SPAN data-contrast=\"auto\">it</SPAN><SPAN data-contrast=\"auto\">,</SPAN><SPAN data-contrast=\"auto\"> so you can compare approaches.</SPAN><SPAN data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:0,&quot;335559740&quot;:240}\"> </SPAN></P>\n<H2><STRONG><SPAN data-contrast=\"auto\">1. Overlay vendors fix only the easy stuff leaving big accessibility gaps.</SPAN></STRONG><SPAN> </SPAN></H2>\n<P><SPAN data-contrast=\"auto\">H</SPAN><SPAN data-contrast=\"auto\">ere is how they generally work: you add </SPAN><SPAN data-contrast=\"auto\">a </SPAN><SPAN data-contrast=\"auto\">line of code</SPAN><SPAN data-contrast=\"auto\"> to your website</SPAN><SPAN data-contrast=\"auto\"> </SPAN><SPAN data-contrast=\"auto\">that</SPAN><SPAN data-contrast=\"auto\"> calls the vendors&#39; server to load a set of fixes they have  prepared</SPAN><SPAN data-contrast=\"auto\">.  It </SPAN><SPAN data-contrast=\"auto\">also </SPAN><SPAN data-contrast=\"auto\">includes </SPAN><SPAN data-contrast=\"auto\">an icon </SPAN><SPAN data-contrast=\"auto\">on your page </SPAN><SPAN data-contrast=\"auto\">which opens</SPAN><SPAN data-contrast=\"auto\"> an overlay (typically they will use a little blue man</SPAN><SPAN data-contrast=\"auto\"> which is the symbol for accessibility</SPAN><SPAN data-contrast=\"auto\">). The fixes loaded are only </SPAN><SPAN data-contrast=\"auto\">for </SPAN><SPAN data-contrast=\"auto\">attributes and tags </SPAN><SPAN data-contrast=\"auto\">on elements.

People with disabilities who require assistive technology to use and navigate websites already have preferred assistive technology</SPAN><SPAN data-contrast=\"auto\"> that</SPAN><SPAN data-contrast=\"auto\"> they use every</SPAN><SPAN data-contrast=\"auto\"> </SPAN><SPAN data-contrast=\"auto\">day</SPAN><SPAN data-contrast=\"auto\">. They have invested their time to learn how to use it and are likely most comfortable using their own devices to navigate the Web. Their devices are set up to </SPAN><SPAN data-contrast=\"auto\">do </SPAN><SPAN data-contrast=\"auto\">the things they need such as, text-to-speech, zoom, color contrast</SPAN><SPAN data-contrast=\"auto\">,</SPAN><SPAN data-contrast=\"auto\"> etc. An overlay attempts to </SPAN><SPAN data-contrast=\"auto\">replace the functionality of these devices.</SPAN><SPAN> </SPAN></P>\n<P><SPAN data-contrast=\"auto\">To use the &quot;text-to-speech&quot; feature in an overlay</SPAN><SPAN data-contrast=\"auto\">, the person requiring the assistive technology </SPAN><SPAN data-contrast=\"auto\">must</SPAN><SPAN data-contrast=\"auto\"> turn off their own, preferred screen-reader and rely solely on the overlay. </SPAN></P>\n<P><SPAN data-contrast=\"auto\">Joe </SPAN><SPAN data-contrast=\"auto\">DiNero</SPAN><SPAN data-contrast=\"auto\"> who heads the </SPAN><SPAN data-contrast=\"auto\">UsableNet&#39;s</SPAN><SPAN data-contrast=\"auto\"> User  </SPAN><SPAN data-contrast=\"auto\">Testing </SPAN><SPAN data-contrast=\"auto\">group is a </SPAN><SPAN data-contrast=\"auto\">long</SPAN><SPAN data-contrast=\"auto\">-</SPAN><SPAN data-contrast=\"auto\">time</SPAN><SPAN data-contrast=\"auto\"> </SPAN><SPAN data-contrast=\"auto\">screen reader </SPAN><SPAN data-contrast=\"auto\">user </SPAN><SPAN data-contrast=\"auto\">and</SPAN><SPAN data-contrast=\"auto\"> a teacher at  the Helen Keller </SPAN><SPAN data-contrast=\"auto\">Institute </SPAN><SPAN data-contrast=\"auto\">in New York</SPAN><SPAN data-contrast=\"auto\">.  He </SPAN><SPAN data-contrast=\"auto\">explains, </SPAN></P>\n<P style=\"padding-left: 40px;\"><SPAN data-contrast=\"auto\">&quot;Using the overlay screen reader instead of my regular screen reader locks me into a small set of features such as arrow, tab and maybe heading navigation. </SPAN><SPAN data-contrast=\"auto\">When </SPAN><SPAN data-contrast=\"auto\">I</SPAN><SPAN data-contrast=\"auto\"> use my screen reader on a regular site that has </SPAN><SPAN data-contrast=\"auto\">been properly coded or fixed for accessibility,</SPAN><SPAN data-contrast=\"auto\"> I can access any form control on the screen (buttons, edit fields, </SPAN><SPAN data-contrast=\"auto\">aria controls, etc.) </SPAN><SPAN data-contrast=\"auto\">and I have the </SPAN><SPAN data-contrast=\"auto\">ability to pull up a list of links on the page.
