CSS Question

Child div in parent div, float:left

Please take a look at my code: http://jsfiddle.net/XptrZ/
Why are'nt the blue divs inside the red one, and why the red one has height=0.
How can I solve this?
Thanks

Answer

add overflow: hidden to parent

.parent {
  background-color: gold;
  border: 1px solid gold;
  position: relative;
  overflow: hidden
}

.child {
  float: left;
  width: 100px;
  height: 100px;
  display: block;
  margin: 10px;
  background-color: pink;
  border: 1px solid #999;
}
<div class="parent">
  <div class="child">div1</div>
  <div class="child">div2</div>
  <div class="child">div3</div>    
</div>
