Hi,

the first task of this challenge is asking you to select all the list item inside an element with ID "gallery"

@media screen and (min-width: 480px) {
  #gallery li { /* to select the id you need to use the # symbol before the id */
    width: 28.3333%;
  }
}

the second task is asking you to clear the left side of every 4th list item in the element with the id of "gallery": 

@media screen and (min-width: 480px) {
  #gallery li {
    width: 28.3333%;
  }
  #gallery li:nth-child(4n) { /* this is the correct pseudo selector, with an hyphen between "nth" and "child" */
    clear: left;
  }
}

Thanks, I was forgetting the dash between the selectors.
