People with disabilities (mostly vision impaired) browse the internet with "just a keyboard" or a screen reader. It's quite cumbersome, but for some people, that's the best they can do.

At a previous job, we had to follow their extensive rules for making everything accessible. A few things that I can remember:

* minimum contrast ratio

* support for the high-contrast mode that some browsers have

* screen reader support for every UI element - this requires a ton of different things

* everything must be usable without a mouse

There were tools to check for a lot of this. There was a separate team of accessibility people who would check the result and create tickets for things that were not good enough.

It was annoying when the designers specified low-contrast colors, then we'd build it with the colors specified by the designers, and then the tool tells us the colors are unacceptable. Why can't the designers check the contrast ratio of their colors?

Testing with a screen reader was extremely annoying (because it reads a description of the currently focused item), but it gave me a lot of empathy for the poor people for whom this is the only way to use a web UI.
