title: Fire jQuery when breakpoint is reached
body: <p>I have a responsive design with multiple breakpoints. Some of the block dimensions in the content are calculated with jQuery. When the viewport changes these dimensions change thus the calculation should be run. How can I fire these events when the dimension of the reference element changes? The reference element changes when a breakpoint is crossed.</p>
  
  <p>I've looked at the "orientationchange" event but it's not having the results I need.</p>
