title: Clearing space between two divs
body: <p>Could anyone please help me with the following problem?
  How can I clear the space between div "top" and div "middle"? This is just a portion of my HTML code. In the browser, I can see a white space between the two divs. How can get rid of the space?</p>
  
  <pre><code>&lt;div class="container"&gt;
          &lt;div class="top"&gt;
  
          &lt;/div&gt;
  
          &lt;div class="middle"&gt;
  
          &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
