title: jQuery - re-use CSS value on another element
body: <p>I have a background colour set on a series of buttons, <code>.button1, .button2., .button3 &amp; .button4</code>. Each of these buttons has a different background colour set in CSS.</p>
  
  <p>I want to use jQuery to detect the background colour of the button when it is clicked and apply that colour to <code>.toolbar</code>.</p>
  
  <p>Is this possible?</p>
