title: i made a "highlight" class in html, and when I use it on my paragraph, the paragraph's margin changes
body: <p>I have just started html 3 weeks ago, and when I started I learned inline style instead of the preferred external style, but I now understand external. Forgive me if I use incorrect terms for certain actions. I have created a "highlight" class in my style tag and it works by changing the background color yellow. When I assign class to the my paragraph tag, the margins of the paragraph change.</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>.highlight {
    background-color: yellow;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link rel=stylesheet type=text/css href=http://www.derekowens.com/ch06.css&gt;
  
  &lt;h1&gt;test test test test test test test test test test test test test test test test test test test test test test test test test&lt;/h1&gt;
  &lt;p&gt;test test test test test test test test test test test test test test test test test test test test test test test test test&lt;/p&gt;
  &lt;p&gt;test test test test test test test test test test test test test test test test test test test test test test test test test &lt;/p&gt;
  &lt;p class="highlight"&gt;test test test test test test test test test test test test test test test test test test test test test test test test test.&lt;/p&gt;
