<p>getDimensions() has been called <span id="calls">0</span> times</p>
<p>The current page size is <span id="width"></span>px by <span id="height"></span>px.</p>
              var w = document.querySelector("#width"),
		h = document.querySelector("#height"),
    c = document.querySelector("#calls"),
    timeout = false, // holder for timeout id
    delay = 250, // delay after event is "complete" to run callback
    calls = 0;

// window.resize callback function
function getDimensions() {
  w.innerHTML = window.innerWidth;
  h.innerHTML = window.innerHeight;
  calls += 1;
  c.innerHTML = calls;

// window.resize event listener

	// clear the timeout
  // start timing for event "completion"
  timeout = setTimeout(getDimensions, delay);
