Code Challenge Pseudo-Class Selectors 2/4

Hi, I made a guess at the right answer, and it actually passed although I wasn't really expecting it to. Just want to ask other people if its the best way to do it?


Create a new rule that targets the 3rd list item only. Set the background color to the HEX value FF6347.

:nth-child(0n+3){ background-color: #FF6347 }

sorry bad english, not my native language.


nth-child(an+b) -> B = initial count and A = the order, in this case, you are setting that the background-color will start on the thir element and them all above, the right for your question is nth-child(3) { background-color: #FF6347 }

Hi Andrew,

You would want to simplify it as Gabriel has shown. Since it's 0n you could simply drop that off because it's not going to do anything. You would only need the an part when you need to select multiple children.


b is the starting child and then a is what you keep adding or subtracting to get the rest of the children.

Thanks guys.
