title: Place div in left bottom corner
body: <p>I want to place div in left bottom corner. I write css like that:</p>
  
  <pre><code>#announcement{
    position: relative;
    bottom: 0px;
    left: 0px;
    width: 50%;
    margin-left: 10px;
  }
  </code></pre>
  
  <p>I'm not the master of css and I'm not about this solution...</p>
