I don’t have time to do as many conference talks these days but @cssday.nl always has a special place in my heart. It’s such a fantastic conference, both for the content and the community. If you can go, don’t miss it!

My career highlight was getting to talk at CSS Day a few years ago, so I'm so excited to be heading back this year, alongside so many other great speakers.

So happy to be back on the CSS Day stage this June with so many other fantastic speakers. And I can't wait to show what I've been working on the last year or two. Yes it will be about Doom, Lasers and CSS, and so much more. ✨

I do feel I've hit peak talk title with "CSS Doom Laser".

So we sent out the mailing yesterday, and where we expected to sell about 30-35 of the early-bird tickets, we sold all of them plus a few regular ones!

So no more early-bird tickets, we're afraid.
