I presented an afternoon workshop on accessibility for WordCamp Europe in Belgrade. I wrote it to include group exercises that did not involve a computer. As you can see in the slides, there is plenty of technical information (too much for the session, it turned out). I may have been overwhelmed by my desire to cover some new WCAG 2.1 material.
