Hi William,

You need to target every fourth list item (4, 8, 12 ...). Your code only affects the fourth item (4).

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

CSS will substitute n with 1, 2, 3... so it means 4*1, 4*2 and so on

Try li:nth-child(4n) instead of li:nth-child(4).

To select the every fourth element you need to use the 'n' . In the following example I select all the multiple of 4. You can read more about :nth-child here and here

@media screen and (min-width: 480px) {

#gallery li { width:28.3333%; } 
#gallery li:nth-child(4n) { clear: left; }

}
