Back in April I went to Beyond Tellerrand in Düsseldorf. I initially planned on going as an attendee, but when organizer Marc asked me to speak I couldn’t say no …

New Blog Post: “Do Websites Need to Function Exactly the Same on Every Platform?”

(Betteridge’s Law of Headlines applies)

While we’ve accepted that websites don't need to look the same everywhere, we seem to be stuck on a new hurdle: the idea that websites need to function the same everywhere.

At CSS Day, “YouTube guy” Kevin Powell showed a lot of demos that relied on the advanced attr() function. In one of the examples he used attr() to set view-transition-name values — a technique I covered in my article on advanced attr() function.

But then during the Q&A, Cyd Stumpel wondered if he couldn’t just use match-element there.

The short answer to that question is yes. The longer answer is … It Depends™

New Blog Post:

View Transitions: Should you use the new `attr()` or `match-element` for the `view-transition-name`?

Well … It Depends™

And, do want me to speak about CSS DOOM at your conference, DM me!

It's been a great year for conferences.

I've spoken at @btconf and @cssday and I've been so lucky to attend so many others, like State of the Browser, Web Day Out and Smashing Conference.

It's sharing knowledge, learning and getting inspired. But mostly the community.

I will be posting about some conference that you should visit this fall. I will be at all of them – either organising myself or speaking. If you have any more tips for some great conferences that I should visit, let me know!

Today exactly 10 years ago, I spoke at CSS Day.

Around that time I created a list of a handful of conference that I would love to speak at. And I am so lucky that was able to tick off most of them over the last 10 years. I even got to speak again at CSS Day last week.

Just one left... for now.

New demo: Animated CSS Grid Layout.

https://codepen.io/bramus/pen/ogBYjgm

Here’s the thing, though: No View Transitions. Heck, no JS at all!

Instead, it uses Anchor Positioning to anchor the cell contents to the cell. Then, CSS transitions are used to animate the contents to their new location as the grid re-layouts.

Here's that calc-size() article @argyleink mentioned just now.

Animate to `height: auto` is possible nowadays!
