Sessions
Since the end of June 2025, many products have to be accessible. Larger products often use component systems whose smallest building blocks are web components. And these, of course, must also be accessible.
In this talk, you'll learn which technical pitfalls to look out for. We'll explore the oddities of the Shadow DOM and look at component semantics. A complete implementation also includes tests—and there are a few things to consider here, too. Finally, we'll look at how we can document the accessible use of our components.
Manual testing doesn't sound sexy, but it's unfortunately necessary for accessibility. Only some of the issues can be detected automatically; we have to fix the rest ourselves.
I'll take you on a journey through the land of barriers. In a live demo, we will look at how to find dead ends for keyboard users, how to identify contrast problems, spot structural errors, and much more.
The session gives you an insight into the most important points and serves as a starting point for your own manual tests.
