title: Css calling class into other style
body: <p>I don't understand why this doesn't work</p>
  
  <pre><code>.mix{
    -moz-border-radius: 5px 5px;
    border-radius: 5px 5px / 5px 5px;
    -moz-box-shadow: 2px 2px 2px #888;
    -webkit-box-shadow: 2px 2px 2px #888;
    box-shadow: 2px 2px 2px #888;
  } 
  #adm_content_login, .mix{
    top:100px;
    position:relative;
    width:450px;
    height:200px;
    margin:auto;
    background-color:#ccc;
    text-align:center;
    border:5px solid #111;
  }
  </code></pre>
  
  <p>When I try to call a class into another class with <code>adm_content_login, .mix</code> , because there is no need if I use this code each time I have the same content I have in the <code>.mix</code>. I don't understand what's wrong with this code. The CSS works if I put it into <code>adm_content_login</code>, but if I try using this method it doesn't work.</p>
