# Cheatsheets for flex, grid, anchor positioning and invoker commands

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](/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.

The cheatsheets aren't Polypane-specific, they're just nice-looking references for these topics that (for the print versions) you can keep on your desk and refer to for a quick lookup of 'how to do that thing again'.

## The cheatsheets

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](/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).
