Learn CSS Flexbox by Building a Photo Gallery: Step 20

Hello everyone, I am stuck on Step 20 of the CSS Flexbox lesson

This is my code:
.galery: :after{
width: 350px;
content: “”;

But I keep getting the same error message and don’t know what to do:

You misspelled gallery. Also there shouldn’t be space between the two colons for ::after

Thanks! The :: fixed it, the gallery thing wasn’t even noticed by the step haha

It would have been though. The coding can only give you one fault at a time.
