787 PointsCode challenge says my code is wrong when I think it's correct. Not sure what's wrong. Please help!
A code challenge is telling me to make a media enquiry with a selector of a gallery on my basic HTML page, with the task of clearing every 4th item on the left side of the list. It tells me my code is incorrect, but is it? I've retyped it all out numerous times after rewatching the video over and over again, but it's not letting me progress. Please help!

28,690 PointsHi Chris,
In the posted code there is space between nth
and child
. nth-child
is a hyphenated phrase so replace the space with a hyphen (-
) instead.

787 PointsThanks so much! It's astounding that one little thing can cause everything not to work. I would've never caught that.
