title: How to center text inside of font-awesome circle
body: <p>I have css/html below and I want to center the text inside of the circle. I can calculate the correct margin if there is only 1 digit, but I would like it to always work, even if there are two or three digits. Anyone have a good solution for this?</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.circle-stack {
      position: absolute;
      display: inline-block;
      width: 10px;
      height: 10px;
      top: 25px;
      left: 5px;
  }
    
  .fa-circle-thin,
  .points-indicator {
      position: absolute;
  }
  .fa-circle{
    font-size: 16px;
    color: #c0cff6;
  }
  
  .points-indicator {
    color: #1f0e3e;
    font-weight: bold;
    top: 1px;
    left: 4px;
    width: 5px;
    height: 5px;
    font-size: 10px;
    line-height: 16px;
    text-align: center;
  }</code></pre>
