title: Broken button styling in Tailwind CSS
body: <p>According to documentation, this is how you style a button with Tailwind:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;button class=&quot;py-2 px-4 bg-green-500 text-white rounded-lg shadow-md hover:bg-green-700 focus:outline-none focus:ring-2 focus:ring-green-400 focus:ring-opacity-75&quot;&gt;
    Click me
  &lt;/button&gt;
  </code></pre>
  <p>This shouldn't require any special configuration.</p>
  <p>But when I try this code in <a href="https://play.tailwindcss.com/mOHj54v9iv" rel="nofollow noreferrer">Tailwind Play</a>, the button doesn't even get rendered.</p>
  <p>What gives?</p>
  <p>Many thanks in advance.</p>
