This seems to be a bug with dark mode and short-answer questions, showing white on white @ascholerChemeketa . You can switch to Light mode by clicking on the Aa button at the top and then Light.
See
Project 1.6.4
https://runestone.academy/ns/books/published/csawesome2/topic-1-6-compound-operators.html?mode=browsing#challenge1-6 in dark mode.

@ascholerChemeketa - I just fixed the css for shortanswer.

[ascholerChemeketa]

lol, you can ignore the PR I just made then

I liked your solution better. I used a variable for the background-color, but yours seems to work just as well.
