What has been tested?
Dizzy components as a rule target the WCAG 2.1 AA conformance level. This means I aim to provide you with a set of components that just work for all users, regardless of how they interact with the web.
AA Conformance
Conformance to WCAG is in some respects a constantly shifting job for you, the end-developer. Although I can provide you with components that I have tested and believe to be, in isolation, fairly accessible for most internet users, I am, at the end of the day, providing you with low-level building blocks that you will combine in new and exciting ways in your own application. This means that when you combine these components together in new ways, it is possible for you to create experiences that are not accessible to all users or do not meet the WCAG AA conformance level.
So long story short, accessibility is extremely important to me, and it's something I take very seriously, and if you purchase a license for Dizzy you can be assured I've done everything I can to make sure the components you're getting have been tested, in isolation, in all the ways I can think of doing. Ultimately, it is up to you to do your own testing on your final application and ensure that your application itself is still meeting the level of accessibility you need.
I would also encourage you to use the W3C accessibility statement generator for your site or application.
