So, I just mixed up the order of the conditional expression and the step statement in a Javascript for loop. I suppose it'd been a while, heh. Thankfully, was able to sort it out pretty quick.
been doing web dev for a decade and i constantly have at least 5 MDN tabs open at all times.
i still write both justify-content and align-items and just delete whichever one didn't work...
btw i would love a helpful mnemonic for remembering which is which lol
