title: flexbox - Column contains div rows not working
body: <p>Purpose: a flexbox page with a background image (cover) that may grow in height when the screen shrinks forcing elements to wrap; But it has header bar at the top.</p>
  
  <p>I made the whole screen a column with a background image.
  First element in the column: a mock header bar.
  Second element is SUPPOSED to be a div - flex-direction: row, but the colored divs inside still behave like it's in a column.</p>

  <pre><code>    html, body { box-sizing: border-box; height: 100%; width: 100%;
    margin: 0; padding: 0; border: 0; cursor: default }
  
  .workspace {
    background: url("../../../assets/Images/WhatIsHunter2.jpg") no-repeat center center fixed;
    background-size: cover;
    height: 100vh;
    width: 100vw;
  
    h1 {
      color: #E0B228;
    }
  
    h2 {
      color: #2856E0;
    }
  }
  </code></pre>
  
  <p>The HTML:</p>
  
  <pre><code>&lt;div class='workspace' [ngStyle]="{'display': 'flexbox', 'flex-direction': 'column'}"&gt;
    &lt;div [ngStyle]="{'width': '100vw', 'height': '60px', 'background-color': 'beige'}"&gt;
      This is its own row at the top of the column - a header bar
    &lt;/div&gt;
    &lt;div [ngStyle]="{'margin-top': '20px', 'display': 'flexbox', 'flex-direction': 'row', 'justify-content': 'space-evenly'}"&gt;
      &lt;div [ngStyle]="{'width': '100px', 'height': '100px', 'background-color': 'red'}"&gt;
      &lt;/div&gt;
      &lt;div [ngStyle]="{'width': '100px', 'height': '100px', 'background-color': 'green'}"&gt;
      &lt;/div&gt;
      &lt;div [ngStyle]="{'width': '100px', 'height': '100px', 'background-color': 'blue'}"&gt;
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
