title: Click/toggle to reveal more
body: <p>I have some content that I want only a few lines to be shown along with a "read more" button and then when a user clicks on the read more button, the rest of the content will be revealed by the content div dropping down (extending its height) and then the read more button would be replaced with "close".</p>
  
  <p>Does anyone know of any JS Fiddle demos or tutorials with examples of similar things?</p>
