It should pass if you remove the space between nth-child and (3n+4)

Holy shit, that was frustrating. Thanks man <3

I've definitely been there - driven myself crazy only to find that there's an errant space somewhere

Hi Andre,

Remove the space between the psuedo class and the params in parenthesis, other than that you have the correct CSS written as is.

Take care!
