This is going to be an unusual blog because most of it will be in a footnote of sorts. The legal part of the blog is easy. If your business wants to avoid getting sued under the ADA because of an inaccessible website an accessibility overlay or widget isn’t going to help you. I can say this with some certainty because in the last two weeks alone five lawsuits have been filed against businesses that use an accessibility widget or overlay on their websites.* I also know why this is the case. The law firms who file website accessibility lawsuits and their pet clients start the process of finding a target using automated tools that scan for compliance with the technical requirements of the Web Content Accessibility Guidelines 2.0 or 2.1. I have used those tools on websites using an overlay or widget and they almost always flag errors of some kind. There is a lot a dispute about the effectiveness of these scanning tools, but effective or not getting flagged by one of them is an invitation to a lawsuit. If a widget doesn’t fix the errors plaintiff’s lawyers can find using automated tools it won’t prevent a lawsuit. The conclusion is simple. If avoiding litigation is your goal an overlay or widget won’t do the trick. More
