title: How to change bootstrap typographic measurement in the appropriate way?
body: <p>Currently Bootstrap 3 used <code>html {font-size: 62.5%;}</code> and then </p>
  
  <pre><code>body {
  
    font-size: 14px;
    line-height: 1.42857143;
  
  }
  </code></pre>
  
  <p>and than px everywhere for typography </p>
  
  <pre><code>h1,
  .h1 {
    font-size: 36px;
  }
  h2,
  .h2 {
    font-size: 30px;
  }
  h3,
  .h3 {
    font-size: 24px;
  }
  h4,
  .h4 {
    font-size: 18px;
  }
  h5,
  .h5 {
    font-size: 14px;
  }
  h6,
  .h6 {
    font-size: 12px;
  }
  </code></pre>
  
  <p>And in current condition if I want to make default <code>font-size</code> to <code>16px</code> should I also increase the <code>px</code> size of all heading levels like <code>36</code> to <code>38</code> for <code>h1</code> and also change the <code>line-height</code> which is <code>1.42857143</code> for <code>14px</code> <code>font-size</code></p>
  
  <p><strong>Or</strong> I can just change <code>html {font-size: 62.5%;}</code> to something else and no editing required for <code>body</code>, <strong>heading</strong> and <strong>line height</strong></p>
