Page Scroll Reading Progress Indicator with Progress.js

Description:

Progress.js is a small JavaScript library that generates an animated, circular, SVG based progress bar to indicate the reading progress as you scroll down the page.

How to use it:

Load the Progress.js at the end of the document.

<script src="path/to/progress.min.js"></script>

Create a circular progress bar using SVG element.

<div class="progress-indicator">
  <svg>
    <g>
      <circle cx="0" cy="0" r="20" stroke="black" class="animated-circle" transform="translate(50,50) rotate(-90)">
    </g>
    <g>
      <circle cx="0" cy="0" r="38" transform="translate(50,50) rotate(-90)">
    </g>
  </svg>
  <div class="progress-count"></div>
</div>

A little CSS to style the progress indicator.

.progress-indicator {
  position: fixed;
  top: 10px;
  right: 20px;
  width: 100px;
  height: 100px;
  z-index: 20;
}
.progress-count {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  text-align: center;
  line-height: 100px;
  color: #0082FF;
}
svg { position: absolute; }
circle { fill: rgba(255,255,255,0.9); }
svg .animated-circle {
  fill: transparent;
  stroke-width: 40px;
  stroke: #0A74DA;
  stroke-dasharray: 126;
  stroke-dashoffset: 126;
}

That’s it.  The progress indicator will auto update based on the scroll depth.
