title: Make smaller button in bootstrap
body: <p>I use bootstrap 3 buttons and I want to modify the size to smaller, I've tried with the following which doesn't work</p>
  
  <pre><code>.btn-sml {
      padding: 10px 10px;
      font-size: 22px;
      border-radius: 8px;
  }
  </code></pre>
  
  <p>There is a better way to achieve this ? </p>
