Global Accessibility Awareness Day 2019

I kind of missed it this year. I was presenting at YGLF and was invested in the other talks, so my annual tweet thread of my accessibility posts since the previous GAAD did not come out on time. Instead I filled up timelines last night. Below are eight tweets with…

Avoid Default Field Validation

HTML5 gives us form field validation for free. The problem is that the default messages browsers provide are not always useful and typically do not work with assistive technology.
