Changing the width or zooming in and out changes the number of columns (nice!), but the max seems to be 4. Is that a hard limit? Seems like a responsive UI should respect wider screens in landscape.
Nice work, btw.
I got all of the responsiveness for free using CSS grid! Definitely recommend checking it out if you haven't yet
Figured something like this would be a little overwhelming https://imgur.com/nx3hISb
