Why doesn't nth-of-type/nth-child work on nested elements?

Question

I\'m trying to change the style of odd divs that are inside a div. For some reason the nth-of-type(odd) is affecting all my divs when it\'s inside another div.

:nth-of-type() is similar to :nth-child() in that they must all be from the same parent. If you need those wrapper divs, use :nth-of-type() on those wrappers instead:

div.post:nth-of-type(odd) .video-entry-summary {
    width:214px; 
    height:210px; 
    margin-left:0px;
    float:left;
    position:relative; 
    overflow:hidden; 
    border:1px solid black; 
    background:#ccc; 
}

If all the siblings are .post, use :nth-child() instead to prevent confusion with what :nth-of-type() really means:

.post:nth-child(odd) .video-entry-summary {
    width:214px; 
    height:210px; 
    margin-left:0px;
    float:left;
    position:relative; 
    overflow:hidden; 
    border:1px solid black; 
    background:#ccc; 
}

.video-entry-summary {
  width: 214px;
  height: 210px;
  margin-left: 10px;
  float: left;
  position: relative;
  overflow: hidden;
  border: 1px solid black;
}

.post:nth-child(odd) .video-entry-summary {
  width: 214px;
  height: 210px;
  margin-left: 0px;
  float: left;
  position: relative;
  overflow: hidden;
  border: 1px solid black;
  background: #ccc;
}
