title: Parent div is smaller than child div?
body: <p>here's my question, i want to fill the <code>content div</code> with white. BUT when i do it , its not filling the whole div. The child div are more bigger and they go over the parent div (content). I want that the content div cover all the child div.</p>
  
  <p>Here's my code</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>#content {
    width: 100%;
    min-height: 400px;
    height: auto;
    max-height: 2000px;  /* ONLY FOR THE MOMENT */
    margin-top: -7px;
    background:white;
  }
  #fastMenu {
    float:left;
    width: 200px;
    height: 100%;
    margin-top: 20px;
  }
  #contenu {
    float:left;
    width: 430px;
    height: 100%;
    margin-top: 20px;
    background:white;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id = "content"&gt;
    &lt;div id = "fastMenu"&gt;
