title: Set HTML element visibility by radio button state
body: <p>I'd like to hide/show a <code>DIV</code> based on the state of a radio button.</p>
  
  <p>I know I can add a listener to the radio button and show/hide it whenever it's selected or unselected (like <a href="https://stackoverflow.com/a/18307407/416300">this</a> answer).</p>
  
  <p>Is there a way to bind the <code>Div</code>'s <code>display</code> attribute to the radio-button's <code>:checked</code> attribute, something like <code>$("#myDiv").visibility($("#myRadio").is('checked'));</code> ?</p>
  
  <p>In other words - can I data-bind the display/visibility to the radio button's state?</p>
  
  <p>Maybe this can be done easily in css?</p>
