title: Fixing the 1px gap of 3 container with width of 33.333%
body: <p>This is hard to explain in words but I see a 1 pixel line of 3x containers of width of 33.3333% and I can't change that as its part of <code>material-ui</code></p>
  
  <pre><code>&lt;div class="container"&gt;
      &lt;div class="panel" style="width:width of 33.3333%"&gt;
          &lt;!-- Content here --&gt;
      &lt;/div&gt;
      &lt;div class="panel" style="width:width of 33.3333%"&gt;
          &lt;!-- Content here --&gt;
      &lt;/div&gt;
      &lt;div class="panel" style="width:width of 33.3333%"&gt;
          &lt;!-- Content here --&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>So here what I'm getting, and i only because its 33.333%, set it to 25% or 50% and the problem goes away, i have marked the pixel line with a bit of red (paint).</p>

  <p>This is the <code>material-ui</code> <code>&lt;gridList&gt;,</code> <code>&lt;GridItem&gt;</code> and <code>&lt;Cards&gt;</code> and its quite fustrating.</p>
  
  <p><em>EDIT</em> </p>
  
  <p>Trying out <code>33.33 / 33.33 / 33.34</code> still returning 1px gap! </p>
