title: How to remove space between bootstrap divs
body: <p>I have three <code>div</code>s like this:</p>
  
  <pre><code>&lt;div class="container-fluid"&gt;
      &lt;div class="header"&gt;
          Welcome
      &lt;/div&gt;
      &lt;div class="navbar"&gt;
          Menu
      &lt;/div&gt;
      &lt;div class="content"&gt;
          Website content
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Now, the first <code>div</code> <code>class="container-fluid"</code> is stretched on all browser window. The next <code>class="header</code> has <code>padding</code>/<code>margin</code> of some pixels from his parent element. Now I´d like this <code>div</code> to stretch all browser window out. But I also don´t want next <code>class="menu"</code> or <code>class="content"</code> to be stretched out.</p>
  
  <p>How may I solve this?</p>
