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…

Selfish Accessibility — YGLF Vilnius

I (and the audience) survived my talk today. As our mutual reward, I offer my slides. All the links turned white onupload, so they are nearly impossible to read. I am sharing it now because you can at least hover over them or follow them, otherwise you might have to…

Details / Summary Are Not [insert control here]

Once major browsers started supporting <details> & <summary> developers immediately started to play with them to see what sorts of patterns they could enhance or replace. This is a good thing.
