On The “Learn CSS Firebox by Building a Photo Gallery” Section of the curriculum I believe there is some type of error. I have done this a million times now and I am certain I am correct, however they will not pass it. See attached photos for instructions followed by my code!
Thank you

The problem will be that the ::after pseudo-element (and other pseudo-elements) needs to be attached to the selector, without space between them.

.example1::after {
content: "This is valid";
}
.example2 ::after{
content: "This is not valid";
}
