I've seen several pages you've editted putting punctuation outside of quotation marks. And I do it too occasionally (just look at last thing I posted on here right below this one). I remember being taught that punctuation goes inside the quotation marks. Anyway, I found this: https://style.mla.org/punctuation-and-quotation-marks
It seems like a rule that's falling out of style in the digital age, but apparently the traditional rule is that punctuation goes inside the quotes.
