about this site

It's very common to do entire layouts using float. Here is the same layout we did with position earlier, but using float instead.

nav {
  float: left;
  width: 200px;
}
section {
  margin-left: 200px;
}
<div class="clearfix">
<section>

This example works just like the last one. Notice we put a clearfix on the container. It's not needed in this example, but it would be if the nav was longer than the non-floated content.

</section>
