title: Custom cross-browser scrollbar without jQuery
body: <p>CSS scrollbar styling isn't fully supported in all major browsers, so I was wondering, how could it be achieved without the use of jQuery.</p>
  
  <p>Is there a light JS for something like this?</p>
  
  <p>I think, that it's not very effective to use jQuery because of a scrollbar.</p>
  
  <p>looking for pure <strong>javaScript</strong> solution without depending any frameworks like jQuery</p>
