Dynamic Circular Progress Bar with jQuery and CSS3

Just another jQuery plugin which uses JavaScript and CSS3 transforms to draw an animated progress (loading) bar representing a given percent value.

How to use it:

1. Add jQuery library and the jQuery-plugin-progressbar.jsinto your html page.

<script src="//code.jquery.com/jquery-2.1.4.min.js"></script>
<script src="jQuery-plugin-progressbar.js"></script>

2. Create an empty DIV element that will be served as the container for the progress bar.

<div class="progress-bar"></div>

3. Draw a default progress bar inside the DIV element.

$(".progress-bar").loading();

4. The required CSS / CSS3 rules for the progress bar.

.progress-bar {
  position: relative;
  height: 100px;
  width: 100px;
}

.progress-bar div {
  position: absolute;
  height: 100px;
  width: 100px;
  border-radius: 50%;
}

.progress-bar div span {
  position: absolute;
  font-family: Arial;
  font-size: 25px;
  line-height: 75px;
  height: 75px;
  width: 75px;
  left: 12.5px;
  top: 12.5px;
  text-align: center;
  border-radius: 50%;
  background-color: white;
}

.progress-bar .background { background-color: #b3cef6; }

.progress-bar .rotate {
  clip: rect(0 50px 100px 0);
  background-color: #4b86db;
}

.progress-bar .left {
  clip: rect(0 50px 100px 0);
  opacity: 1;
  background-color: #b3cef6;
}

.progress-bar .right {
  clip: rect(0 50px 100px 0);
  transform: rotate(180deg);
  opacity: 0;
  background-color: #4b86db;
}

@keyframes 
toggle {  0% {
 opacity: 0;
}
 100% {
 opacity: 1;
}
}

5. Default plugin options.

// background color
backgroundColor: '#b3cef6',

// progress bar color
progressColor: '#4b86db',

// percentage data to present
// 75 = 75%
percent: 75,

// animation speed
duration: 2000

6. You can also pass the options to the progress bar using html5 data attribute on the DIV element.

<div class="progress-bar" data-percent="60" data-duration="1000" data-color="#ccc,yellow"></div>
