A pure CSS solution to create pretty, fast and responsive bar gauges which can be used for counter, progress bar, or anything else.

How to use it:

Build the Html structure for the gauge.

<div class="container">
  <div class="gauge-a"></div>
  <div class="gauge-b"></div>
  <div class="gauge-c"></div>
  <div class="gauge-data">
    <h1 id="percent">0%</h1>
  </div>
</div>

The required CSS styles.
