title: How to "theme" a Navigation Menu
body: <p>I'm having some difficulty trying to figure out how to "theme" the main navigation menu in Drupal 8 using Bootstrap.  It seems as though the Drupal 8 themes engine overrides anything I try in Bootstrap.</p>
  
  <p>I am trying to make it look something like this:</p>
  
  <pre><code>&lt;nav class = "navbar navbar-default navbar-fixed-bottom" role = "navigation"&gt;
      &lt;div class="container"&gt;
          &lt;ul class = "nav navbar-nav" style="display: flex; justify-content: space-between;"&gt;
              &lt;li&gt;&lt;a href = "#"&gt;ITEM ONE&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href = "#"&gt;ITEM TWO&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href = "#"&gt;ITEM THREE&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href = "#"&gt;ITEM FOUR&lt;/a&gt;&lt;/li&gt;         
          &lt;/ul&gt;
      &lt;/div&gt;
  &lt;/nav&gt;
  </code></pre>
  
  <p>Basically I just want the menu to be fixed to the bottom, to be justified with equal spacing between each menu link, and to be the same width as the container size (not the width of the page).  I have spent two days trying to figure out which part I need to edit, and I have no clue anymore.</p>
  
  <p>Thank you to any brilliant person that can solve my problem.</p>
