Can't get left!!?!

I've gotten my 2 columns to break into three at the breakpoint, but cannot float that 4th item to the left. Seem to have copied the code precisely and cannot ferret out any trouble with the index code, which should just need gallery id to work.

Below, are snapshots, followed by a cut and paste of the code. Apologies for surreal placeholders and thanks in advance for your help!

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

  /*********************************
  TWO COLUMN LAYOUT

  #primary {
    width: 50%;
    float: left;
  }

  #secondary {
    width: 40%;
    float: right; 
  } 



   /*********************************

  #gallery li {
    width: 28.3333%;
  } 

  #gallery li:nth-child(3n + 1) {
     clear: left;
  }  

}




@media screen and (min-width: 660px) {

}
