You’re very close, you just have a couple of syntax errors. Remember, your curly braces should always work in pairs, for every opening curly brace you should have a closing curly brace. Also, I think you have one too many colons before the opening curly brace.
Spaces in CSS selectors actually mean something, so you can’t just add them in there like that. If you want to use a pseudo-class to target an element then it has to be attached to the element (no space between them).
Just curious, did you add that space on purpose or was that just an honest mistake?
This was a frustrating step to just spring this on us without explaining that there was a way to select, for example, all but the last type of something. It came out of nowhere. Suddenly it just says “hey do this” and we didn’t even know it was possible.
