In your second media query you state 48 px, I believe it should be 480px.

Also you can include the :nth-child in your first media query since the rules are the same, no need to make a second.

Happy coding.

First, and foremost both of the steps to the challenge should be done in the same media query. And the second media query you have set up has the incorrect number of pixels as the breakpoint. You've set 48px instead of 480px as the breakpoint. That being said, the code you've written would clear the left of the fourth element. But they want you to clear the left of every 4th element... ie element 4, 8, 12... etc. Take a look at what you need:

@media screen and (min-width: 480px) {
  #gallery li {
    width: 28.3333%;
  }

  #gallery li:nth-child(4n) {
    clear: left;
  }
}

Yes (4n) is the correct argument, simply missed that :P
