Accessibility overlay widgets vs. fixing your site's code
Overlay widgets add a toolbar (text size, contrast and similar) and try to patch problems with JavaScript. They're marketed as a quick fix. Here's an honest look.
What overlays can do
- Offer user preferences such as bigger text or high contrast, though browsers and operating systems already provide most of these.
- Automatically guess some missing alt text or labels.
Where they fall short
- They can't reliably fix keyboard traps, confusing focus order, inaccessible custom widgets, or unclear form errors.
- Automatically generated alt text is often wrong or vague.
- Some screen-reader users report that overlays interfere with their own assistive technology. Many disability advocates have publicly criticised them (see the Overlay Fact Sheet at overlayfactsheet.com).
- They don't make a site legally compliant, and no product can promise that.
The alternative
Most small-business sites have a handful of repeated problems (missing alt text, contrast, labels, icon buttons, heading order) that can be fixed once in the theme or page builder. Fixing the source is usually a few hours' work and helps every visitor.
