title: Hide radio button while keeping its functionality
body: <p>I searched on SO and Google and I couldn't find anything related. Is there any way I can hide the radio button next to an image (that is used as a label for it) but still keep its functionality when clicking on the label?</p>
  
  <p>I have tried several methods but it seems that using <code>display:none</code> or <code>visibility:hidden</code> makes the radio function useless.</p>
