title: jQuery: if checkbox is checked, toggleClass
body: <p>I am a jQuery noob and seems I always will be, been trying to get this simple thing to work. </p>
  
  <p>What I want is, when the checkbox is checked, hide the div with <code>display: none;</code>.</p>
  
  <p>Here's a <a href="http://jsfiddle.net/dDsm2/" rel="nofollow noreferrer">jFiddle</a> example of what I'm making a mess of.</p>
  
  <p>Thanks for any help, or other solutions :) </p>
