title: Spread two images vertically inside one div
body: <p>I have two similar images inside one fixed size div. Images are placed one under another. I want to spread images vertically in order to one img stick to top, and another stick to bottom.</p>
  
  <pre><code>&lt;div style='text-align: center; border: 1px solid black;'&gt;text
      &lt;div style='border:1px solid black;height: 150px;'&gt;
          &lt;img style='float: left; clear: both;' src='http://iconizer.net/files/Sketchdock_Ecommerce_Icons/orig/arrow-up-blue.png'&gt;
          &lt;img style='float: left; clear: both;' src='http://iconizer.net/files/Sketchdock_Ecommerce_Icons/orig/arrow-down-blue.png'&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
