ADA compliance

 There are two really good free websites:

https://wave.webaim.org/

and on Chrome browser, there's the Lighthouse extension plugin.

I'm on both Chrome and Firefox, so I'm using Lighthouse on Chrome, and the first site for Firefox. Apparently, Wave is also available as an extension on Firefox and Chrome.

Here's another site that gives basic info on how to make sure you have ARIA labels for people with sight impairment.

I'm still hacking at Carrd to see if I can make it more and more compliant.
