title: 70% and 30% columns with Bootstrap
body: <p>I got this "test" from a recruiting agency:  </p>
  
  <blockquote>
    <p>Create a page template with two layers, one 70% width and the second
    30% of the page; in the first layer there will be the content, in the
    second the featured image.</p>
  </blockquote>
  
  <p>I was wondering if I can achieve those exact percent with Bootstrap even if it's not meant to be used that way.</p>
