title: How do I remove the white space above my navigation bar?
body: <p>I want to have a navigation bar to have no top border, but even if I set "margin" to 0px, there is a little space.</p>
  
  <p>How would I remove that space?</p>
  
  <p>Code:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>#navigationBar {
    margin: 0px;
    padding: 0px;
    overflow: hidden;
    background-color: #333;
  }
  
  li {
    display: inline;
    float: left;
    display: block;
    color: white;
    text-align: center;
    padding: 14px 16px;
    margin: 0px;
    text-decoration: none;
  }
  
  .active {
    background-color: #999999;
  }
  
  li a {
    display: block;
    color: white;
    text-align: center;
    padding: 14px 16px;
    margin: 0px;
    text-decoration: none;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;nav&gt;
    &lt;ul id="navigationBar"&gt;
      &lt;li class="active"&gt;Site1&lt;/li&gt;
      &lt;li&gt;Site2&lt;/li&gt;
      &lt;li&gt;Site3&lt;/li&gt;
      &lt;li&gt;Site4&lt;/li&gt;
      &lt;li&gt;Site5&lt;/li&gt;
    &lt;/ul&gt;
  &lt;/nav&gt;</code></pre>
  </div>
