Challenge: Learn CSS Flexbox by Building a Photo Gallery - Step 20

Link to the challenge:

that is not css, you will need a class or id before your ::after and then the opening and closing brackets ({}) and then content set to “” (for empty string)

You can use ::after (and ::before) in the same way you add :hover to an element.
As for the part asking to set content to an empty string. You do that the same way you add every other css style.
I’m sure you can complete the challenge once you understand these two points. :+1:
