CSS Day is the annual CSS community conference that brings specifiers, implementors, teachers, and authors together to discuss the current state of CSS, upcoming features, and cool demos.
On 4th and 5th of June 2027 we'll run our thirteenth edition. Do you want to talk about CSS in real life, and not just online? Make friends, not followers? Then come. You'll love it.

From our extensive correspondence with literally none of you we know that you all have pressing life questions such as "How many of my CSS heroes will I meet at CSS Day?" and "How many flamethrowers will they aim at me from stage?"
The answers are lots and probably none, respectively.
You trust us, right? I mean, we're very protective of our target audience.
