title: Preventing Hover event of a Div triggering on parent Div?
body: <p>When I mouseover <code>.mensal</code> DIV it will trigger the mouseover the parent <code>.opera</code> DIV, which seems wrong to me. I just want the "highlight" effect to to work on the child <code>.opera</code> DIV.</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>#operaContent {
    padding: 0 50px 0 50px;
    position: relative;
    overflow: visible;
  }
  #operaContent .opera {
    display: block;
    border: 1px solid #FFFFFF;
    border-bottom: 1px solid #DDDDDD;
    padding: 5px;
    margin-bottom: 10px;
    height: 120px;
    background-color: #0A8ECC;
  }
  #operaContent .opera:hover {
    border: 1px solid #AAAAAA;
    background-color: #DDDDDD;
    cursor: pointer;
  }
  .mensal {
    position: absolute;
    top: 1px;
    left: 8px;
    z-index: 3;
    display: block;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="operaContent"&gt;
    &lt;div class="opera"&gt;
      &lt;div class="mensal"&gt;
        DIV
      &lt;/div&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
