Structural Pseudo-classes Code Challenge Question #3

Im going through just fine and here is my code for each of the first 3 questions. On the (-n+4) part, when I put that in, it tells me that "It looks like Task #1 is no longer passing" ?? But if I change it to something else like (n+4) it just tells me I need to check my selector!

omg what am I doing wrong? To me these selectors are getting crazy hard to remember all of them and no matter what Im going to have to review these before I ever put them in a site lol

li:nth-child(even) { color:white; background-color: #000; }

li:nth-child(3n) { color:white; background-color: #FF6347; }

li:nth-child(-n+4) { color:white; background-color: #FF6347; font-weight:bold; }

Shawn Katzenmeier - Remember to follow the instructions exactly the 3rd step made no mention changing the color or background just the font-weight.

Check out http://nthmaster.com/ to help you get a better grasp on nth-child.

If you are ever having trouble working out a complex nth-child you can always try it out on the nth-child visual calculator

Guil Hernandez - There appears to be a bug for the correctness check on step 2 on this code challenge

the code challenge engine marks li:nth-child(3n) { background-color: #FF6347; } as correct, where it should only allow nth-child(3).

Thanks James! Sometimes its easy to get frustrated and miss little details.

the nth-child calculator is really cool!
