1. Size of elements is here inclusive borders and margins, because of box-sizing: border-box;
2. The elements inside "row-fluid" are div class="span3" (or span6). They are selected with CSS: .row-fluid [class*="span"]
3. Between elements is always the distance: margin-left: 2.564102564102564%;
4. Only the first element in the class has no margin-left: .row-fluid [class*="span"]:first-child {margin-left: 0;}
   So, the first element stays left
5. All the elements have min-height, and stay visible without text: min-height: 30px;
