  Simple javascript solution:

  window.addEventListener('load', function () {
  	function go() {
  		i = i < width ? i + step : 1;
  		m.style.marginLeft = -i + 'px';
  	}
  	var i = 0,
  		step = 3,
  		space = '     ';
  	var m = document.getElementById('marquee');
  	var t = m.innerHTML; //text
  	m.innerHTML = t + space;
  	m.style.position = 'absolute'; // http://stackoverflow.com/questions/2057682/determine-pixel-length-of-string-in-javascript-jquery/2057789#2057789
  	var width = (m.clientWidth + 1);
  	m.style.position = '';
  	m.innerHTML = t + space + t + space + t + space + t + space + t + space + t + space + t + space;
  	m.addEventListener('mouseenter', function () {
  		step = 0;
  	}, true);
  	m.addEventListener('mouseleave', function () {
  		step = 3;
  	}, true);
  	var x = setInterval(go, 50);
  }, true);

  #marquee {
     background:#eee;
     overflow:hidden;
     white-space: nowrap;
   }
