The :nth-child pseudo selector can be a tricky beast.

When you use only a single numeral inside the brackets, it only applies your styling to that specific element. So,

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

will only apply clear: left to the fourth element. To clear every fourth element, you need to use an expression. The general formula is xn+y, where x is the interval and y is the initial offset. So if you were to use 4n+0, it would be applied to every fourth element (:nth-child in CSS starts with 1 in terms of counting child elements unlike most programming languages which start at zero). Similarly, if you were to use something like 3n+2, it would start with the second element and then apply your styles to every third element thereafter.
