Web Accessibility Shortcuts to Avoid
As web-related ADA lawsuits surge nationwide, website owners are desperate for quick and cheap accessibility solutions. Naturally there are a growing number of providers claiming to offer that quick and cheap ADA compliance solution. These fall under the "if it sounds to good to be true" category.
"Overlay" Solutions That Claim to Automagically Make Your Website ADA Compliant
Overlay solutions are automated software solutions, which as we know, can only detect ~30% of WCAG issues. So, right out of the gate these miss ~70% of WCAG elements. This is because the WCAG is nuanced and interpretive. Machines are not good at this.
These solutions typically take the shape of an “accessibility button” that a user needs to be able to find and open (which may not even be possible for some users). The button opens a toolbar with options such as
- Text adjustments - size, spacing, alignment
- Color - contrast, saturation, monochrome
- Adjust curser
- Add focus states
- Screen reader in some cases
Some now incorporate Artificial Intelligence (THE buzzword of 2020), to interpret images and automagically add alt tags, which are labels that describe images. However, as you might guess, accuracy and usefulness for the actual person using a screen reader is low.
Why Overlay Solutions Fail to Deliver True Accessibility
Overlay solutions provide a short-term bandaid. And there are legitimate uses for this approach, such as while a website is being rebuilt or remediated appropriately. They are not long-term solutions that provide significant accessibility or risk of legal actions.
Here is why
Overlay Solutions Lack Manual Testing and Remediation
As already stated, they’re automated, so they miss 70% of WCAG issues. These can only be assessed using manual testing.
The Core Website Remains Legally Exposed
Since the limited “fixes” are only applied after the user finds the button and turns on the layer. Meanwhile the core website is still inaccessible and will test that way when legal trolls visit. So the claims of legal protection are very shallow.
Overlays Override the Users’ Existing Assistive Technology Tools
This is the most significant. Any person with a disability has their favorite set of tools and browser settings already tuned and learned. Forcing a user with disabilities to scrap their tools to then study, learn and customize this new set of toolbar options for each website they visit is a serious barrier. So they really don’t work for the actual people with disabilities. They only serve the interests of the website owner looking to avoid the expense of proper website accessibility.
Overlays Don’t Work Well - if at all- For Mobile
People with disabilities also use their mobile devices to browse websites, and unless heavy customization is applied, any out of the box solution will very likely fail for mobile users.
Overlays Open Security Holes
Here, the website owner is allowing a third party to open a door and inject code into your website. This inherently opens security risks that should be carefully assessed.
Alternate “Accessible” Websites - ABSOLUTELY AVOID!
While this post is focused on overlay solutions, it’s very important to quickly mention this. This really is snake oil. This “solution” provides an “Accessible Website” button that links to a separate website. In practice, these “accessible websites” have different and reduced navigation, features, and content. Thus failing the core intent of the ADA to provide full and equal enjoyment. In this example for a lodging property , the actual ability to book a room is not even offered.
I’ve written previously on why to avoid alternate accessible website, so read that to learn more.
Best-Practices for Delivering a Truely ADA Compliant Website
To make your website accessible to actual people with disabilities there is no alternative to following accepted best practices. Actual 508 and ADA compliance starts with a 3-factor WCAG 2.1 A, AA audit provided by an experienced accessibility consultant who understands both WCAG and programming code.
1. Automated auditing of the entire website
2. Manual testing of select unique pages
3. Assistive technology testing of those same select unique pages and use-cases.
With complete audit reporting, the website can then be property remediated addressing all WCAG 2.1 A, AA violations.
Overlay solutions do have a role in providing a short-term patch. A bandaid to provide minimal accessibility while core WCAG issues are being resolved, or while a new accessible website is being developed. Otherwise these solutions only address the easy to to fix symptoms without treating the root violations.
