I'm trying to make use of flex box layouts to nice up a page. Let's start with a model of the markup, cause the actual page is - quite large.

Code html:
<DOCTYPE !html>
<html>
<head>
	<title>CSS 3 Flexbox</title>
	<style type="text/css">
	  .flex {
		width: 100%;
	    background: blue;
	  }
 
	  .flex >div {
		display: inline-block;
 
	  min-height: 100px;
	  min-width: 24%;
	  margin: 0 auto;
 
	  }
 
	  .nav { 
	    display: block;
		width: 25%;
		float: left;
		background: green; 	    
	  }
	  .search { 
		width: 75%;
		background: purple; 
	}
	  .pagination {
	    width: 75%;
	  background: orange; 
 
	  }
 
	  .product {
		background: red;
 
	  }
 
	</style>
</head>
<body>
 
	<div class="flex">
		<div class="nav">

The green box is my nav, the purple a search bar, orange are the pagination areas. Note how the red products wrap around the nav area -- is this possible with flex layout? I've been playing with this for nearly a day and can't figure it out. If I get a solution before anyone posts one I'll put it here.

(Note that flexboxing this is a nice to do. I still have to get the inline box model to work for IE 8+ and Firefox which don't support flex. There's a lot of margin calculation logic in the code that isn't here in the model to make the whole thing look nicer than the model does)
