Today is Global Accessibility Awareness Day - a great day to be talking about accessibility.
Accessibility is for everyone, it’s not an edge case.
Accessibility is cumulative not binary, the more you do for accessibility the more accessible your site is.
Use semantic HTML, browsers have a lot of accessibility built in.
Make things keyboard operable by using the keyboard from time to time when you’re developing.
Finally, you don’t have to ask permission to make things accessible.
