title: How to make a button fit into an upvote icon
body: <p>I was trying to make a button that has the shape of an icon but the button overflows the icon</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>.upvote, .downvote {
              font-size: 55px;
          }
  
          .up {
              color: green;
          }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"&gt;
  
     &lt;button class="upvote up"&gt;&lt;i class="fa fa-caret-up"&gt;&lt;/i&gt;&lt;/button&gt;
     &lt;a class="upvote up"&gt;&lt;i class="fa fa-caret-up"&gt;&lt;/i&gt;&lt;/a&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>It works fine for <code>a</code> tag but I want to use it in a submit form so I can't use <code>a</code> tag.</p>
