Code challenge: Pseudo-Classes – :nth-child (Task 4)

Hello, on task number 4 I can't get through to the next stage.

The task says: "Finally, create a new rule that targets the last 3 list items only. Set the font size to 30px." http://teamtreehouse.com/library/pseudoclasses-nthchild

I have tried both:

li:nth-child(n+5){ font-size: 30px; }

and

li:nth-last-child(-n+3){ font-size: 30px; }

But all I get is the following error: "Bummer! Check the selector in your CSS. Make sure you set font-size to 30px."

Thanks, Lars

li:nth-last-child(-n+3) { font-size: 30px; }

Check your code, I just did this and it passed

Ok, thanks Daniel. I retook the challenge and now it worked oddly enough.

I don't believe you have to add last-child. Declaring the n as -n will reverse the order of the argument, making you start at the 3rd child from the bottom and go up.
