This report made a big splash last year. It’s a large chunk of research that shows just how terribly the web does with accessibility. It’s been updated this year and (drumroll…) we got a little worse. I’ll use their blockquote:
The number of errors increased 2.1% between February 2019 and February 2020.
From the choir:
Part of me thinks: it’s time for browsers to step up and auto-fix the things they can. But I also think that’s dangerous territory. AMP is a browser vendor’s version of “enough is enough” with poor web performance and I’m not loving how that’s turned out to date. That said, evangelism doesn’t seem to be working.
You can fix your site though. My favorite tool is axe.
