Accessibility Overlay vs. Real Accessibility: Pros and Cons
There is a heated debate in the web community: Should you use an accessibility overlay (a widget), or should you fix the code natively?
The answer is usually both, but you need to understand the trade-offs.
Accessibility Overlays (The Widget Approach)
Pros:
- Speed: Deploys in minutes.
- Customization: Allows users to tailor the site to their specific needs (e.g., Dyslexia-friendly fonts).
- Affordability: Much cheaper than hiring a $200/hr consultant to rewrite your CSS.
Cons:
- Can interfere with Screen Readers: Some heavy “AI” overlays try to “fix” the screen reader experience but end up talking over the user’s native software (like NVDA or JAWS).
- Performance: Large scripts can slow down your site.
Real Accessibility (The Native Approach)
Pros:
- Robustness: Works for every user, on every browser, with every device.
- Legal Gold Standard: This is what WCAG 2.1 compliance tools and auditors actually look for.
Cons:
- Time-Consuming: Requires a deep audit of every page template.
- Expensive: Often requires specialized developer knowledge.
The “Sienna” Middle Ground
We built Sienna to avoid the “bloated overlay” trap. We don’t try to use AI to rewrite your site’s logic. Instead, we provide a lightweight accessibility widget for Webflow and other platforms that focuses on the visual and interaction tools users need, without breaking the native screen reader experience.
Don’t pick a side—choose a strategy that protects your users and your business.
