title: Upgraded from Angular 5 to Angular 6, Bootstrap button styles have no spacing
body: <p>Recently, we upgraded from Angular 5 to Angular 6. </p>
  
  <p><strong>The issue:</strong> Bootstrap button styles now have no margin spacing between them. </p>
  
  <p>Bootstrap Version: <code>3.3.7</code></p>
  
  <p>For example, if in the html you do something like this.</p>
  
  <pre><code>&lt;div&gt;
      &lt;button class="btn btn-success"&gt;Success&lt;/button&gt;
      &lt;button class="btn btn-info"&gt;Info&lt;/button&gt;
      &lt;button class="btn btn-cancel"&gt;Cancel&lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Before we updated, these buttons would have margin space between each.</p>
  
  <p>Just curious if there is something we can update that would fix this or a global CSS style that can be used. </p>
