For CSS Day this year we created a set of cheatsheets explaining Flexbox, Grid, Anchor positioning and Invoker commands.
They came out beautifully and a lot of people really liked them at our booth, so we decided to make them available as free downloads at polypane.app/cheatsheets.
CSS Day swag
This year we had a booth at CSS Day in Amsterdam, and it was a ton of fun to talk to so many Polypane users (the crowd as well as the speaker line-up was full of them!) and to meet so many people for who Polypane was new and who were excited to try it out.

Of course we made sure to bring stickers, badges and pins, but for our booth at CSS Day we also wanted to create some swag that wasn't just 'thing with our logo', but something that you'd actually want to keep and use.
Having recently struggled a lot with Anchor positioning and always forgetting the exact syntax for Grid areas made those easy topics to pick because, if nothing else, we would find them useful ourselves.
Flex to go along with Grid and the very exciting new Invoker commands were natural choices to go along with those two, so that's how we ended up with the four cheatsheets we made.

We had the cheatsheets printed on very nice card stock with a matte finish and rounded corners and wanted to make sure at least some of that came across in the online version, so as you pick one of the cards on polypane.app/cheatsheets you'll see a nice rendering of the card with the same matte finish as you mouse over it. Definitely recommend checking out that page (and bookmarking it for later) if you want to see the cards in all their glory.
If you just want to download them, you can scroll down to download them directly from this page. All downloads are free and print-ready (they have a 3mm bleed and are in A5 format).

We're planning on making them available as printed A5 cards in the future, so if you'd like to be notified when that happens, please sign up for our newsletter and we'll let you know when they're available.
Or catch us at a conference and we'll be happy to give you a set of printed cards for free!
