Web development Blog

Recently, I started a new project. I react to the accessibility of more or less randomly picked websites.

Friends of mine organise the seventh international TYPO3Camp, which takes place in Vienna on October 11th - 13th, 2024. I'm there to give a keynote talk and a workshop.

Once again, I’ve teamed up with my friends at Smashing Magazine 😻 to share with you everything I know about web accessibility testing! In this smashing workshop we’ll talk about automatic and manual testing, screen reader basics, Single Page Applications, Dev Tools, and more.

CSS animations can be composited in three ways: replace, add, and accumulate. The animation-composition property allows you to switch between them.
