title: Confused about flexbox/Angular Material Grid
body: <p>So I'm trying to get this sort of layout using Angular Material Grid (based on flexbox)</p>

  <p>Here's my code now  (the width is width of parent full screen, and height is 700 just to mockup the layout)</p>
  
  <pre><code>&lt;div class="mid-section"&gt;
   &lt;div layout="row" style="width:100%; height:700px;"&gt;
    &lt;!-- Left-hand side --&gt;
    &lt;div layout="column" flex="70"&gt;
      &lt;md-card flex="70"&gt;
        Box 1
      &lt;/md-card&gt;
      &lt;md-card flex="30"&gt;
        Box 2
      &lt;/md-card&gt;
    &lt;/div&gt;
    &lt;div layout="column" flex="30"&gt;
      &lt;md-card flex="30"&gt;
        Box 3
      &lt;/md-card&gt;
      &lt;md-card flex="70"&gt;
        Box 4
      &lt;/md-card&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p></p>
  
  <p>All I'm getting it to do is this -
