// Page layout can be done using mixins applied to your semantic classes and IDs
// For instance this layout defines a two column layout on pages with
// a body class of "two-col".
//
// The markup would look like:
//    <div id="container">
//      <div id="header"></div>
//      <div id="sidebar"></div>
//      <div id="content"></div>
//      <div id="footer"></div>
//    </div>
//
// and the layout would look like:
//    +------------------------+
//    |        #header         |
//    +--------+---------------+
//    |        |               |
//    |#sidebar|    #content   |
//    |        |               |
//    +------------------------+
//    |        #footer         |
//    +--------+---------------+
