First we will add the required CSS and jQuery files to our HTML document

      <link href='css/nprogress.css' rel='stylesheet' />
      <script src='js/jquery-1.10.js'></script>
      <script src='js/nprogress.js'></script>


nprogress.css file contains the styling for the top progress bar, which is

#nprogress {
	pointer-events: none;
	-webkit-pointer-events: none;
#nprogress .bar {
	background: #0D9201;
	position: fixed;
	z-index: 100;
	top: 0;
	left: 0;
	width: 100%;

	right: 0px;
	width: 100px;
	height: 100%;
	box-shadow: 0 0 15px #0D9201, 0 0 10px #0D9201;
	opacity: 1.0;
	-webkit-transform: rotate(3deg) translate(0px, -4px);

	-ms-transform: rotate(3deg) translate(0px, -4px);
	-o-transform: rotate(3deg) translate(0px, -4px);
	transform: rotate(3deg) translate(0px, -4px);

  1. What if I’m using twitter bootstrap and I already have a navigation bar at the top? I want to use this progress bar, but it seems like my navbar is blocking it at the top. I dont’ want to permanently bring the navbar down 2 pixels, but I do want the progress bar to show. Any ideas?

  2. For e-learning courses, can this be easily changed to be a progress bar showing where the user is at within the entire lesson?

    Can you assist in accomplishing this?
