Overlays are a powerful way to check your website using various simulators (like color blindness or dyslexia) or to check your site for things like text contrast, layout issues and other accessibility concerns. There are over a dozen different simulators available to use.

You can find the overlays for each pane above the pane size, by clicking the three-layer icon. If an overlay is active for the current page, a blue dot will be displayed.

Do you have an idea for a useful overlay? Let us know.
