Hi, Jeffrey Watters

  • your pseudo-class selector didn't target the correct elements
  • the challenge only asking for add a clear property that clears the left float.
  img:nth-child(3n+4){
    clear: left;
      }

Thank you for your help. Someday I may start to understand this better. Actually thinking or repeating the class again to get a better grasp on it. I don't remember needing to add the '+' sign in the code. That must be where I got off track.

Thanks again,

Jeff
