title: The 'justify-content' property isn't working
body: <p>I have an odd issue that I'm having trouble with. I've been working on this prototype HTML5 template that uses <a href="https://en.wikipedia.org/wiki/CSS_Flexible_Box_Layout" rel="noreferrer">Flexbox</a>. Though I've been running into one slight problem.</p>
  <p>I'm trying to a small space to the sidebar and content area of the template by applying the &quot;justify-content&quot; property to the parent div. Though it's not adding that space between the sidebar and content area. I'm not sure what it is that I'm doing wrong. So if any could help me that would be great.</p>
  <p>Here's my HTML content:</p>
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang=&quot;en&quot;&gt;
  &lt;head&gt;
      &lt;meta charset=&quot;utf-8&quot;&gt;
      &lt;meta name=&quot;viewport&quot; content=&quot;width=device-width&quot;&gt;
      &lt;script src=&quot;//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js&quot;&gt;&lt;/script&gt;
      &lt;script src=&quot;../scripts/javascript/responsive_drop_down.js&quot;&gt;&lt;/script&gt;
      &lt;link href=&quot;../css/protoflexcss.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;screen&quot;/&gt;
      &lt;title&gt;Welcome to My Domain&lt;/title&gt;
  &lt;/head&gt;
  
  &lt;body&gt;
      &lt;header&gt;
          &lt;h1&gt;This is a placeholder &lt;br /&gt;
              for header&lt;/h1&gt;
      &lt;/header&gt;
          &lt;nav class=&quot;main&quot;&gt;
              &lt;div class=&quot;mobilmenu&quot;&gt;&lt;/div&gt;
                  &lt;ul&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;Home&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;Video&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;Pictures&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;Audio&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;Other Work&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;About Me&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href=&quot;#&quot;&gt;Contact Me&lt;/a&gt;&lt;/li&gt;
                  &lt;/ul&gt;
          &lt;/nav&gt;
          &lt;div id=&quot;wrapper&quot;&gt;
              &lt;article class=&quot;content-main&quot;&gt;
                  &lt;section&gt;
                      &lt;h2&gt;Heading goes here...&lt;/h2&gt;
