Ask HN: How can we make the web more accessible for people with disabilities?

I came across a thread on twitter[0] that was eye-watering and eye-opening at the same time.

Here's an excerpt:

  Today, my dad cried over the phone, he wanted one week where he could use his computer without my help.

  He's blind.
  Each inaccessible webpage tells him, "you aren't welcome in this world."

I'm guilty and i feel ashamed. I'm not a frontend person but I don't recall any of my teams ever receiving a request from a client to check accessibility on an application before, and it's quite easy to take these things for granted.

What are some of the best practices to cover in order to build a more inclusive web and a better user experience, especially for people living with disabilities?
