title: Reduce padding in Bootstrap section element (CSS)
body: <p>I've downloaded the bootsrap theme at this page:
   - <a href="https://startbootstrap.com/template-overviews/scrolling-nav/" rel="nofollow noreferrer">https://startbootstrap.com/template-overviews/scrolling-nav/</a></p>
  
  <p>I don't know how to change the CSS files in order to reduce the padding (or margin if it is that) of the <code>&lt;section id="about"&gt;</code> element (file index.html).</p>
  
  <p>Can anyone indicate me where to go?</p>
  
  <p>Thanks a lot!</p>
