title: bootstrap - _reboot.scss is overriding css
body: <p>Ok I have looked for sometime and have yet to fully understand this file.  I was just about to finish up with a new Website when I noticed that all of the fonts had change from 16px to 1rem, too small for a mobile friendly site.  Why is this happening?? More importantly, how do I stop it?</p>
  
  <pre><code>body {
   font-family: -apple-system,BlinkMacSystemFont,"Segoe UI",Roboto,"Helvetica 
   Neue",Arial,sans-serif,"Apple Color Emoji","Segoe UI Emoji","Segoe UI 
   Symbol","Noto Color Emoji";
   font-size: 1rem;
   font-weight: 400;
   line-height: 1.5;
   color: #212529;
   text-align: left;
  }
  </code></pre>
  
  <p>This is the first time I have ever seen this file.  I would like to know from where it is coming, how to override it and prevent this in the future.</p>
  
  <p>Thanks!!</p>
