title: HTML Active Attribute
body: <p>Buttons have a <code>disabled</code> attribute, which influences its native behaviour. Is it html-syntaxically incorrect to set a <code>active</code> attribute?</p>
  
  <pre><code>&lt;button active&gt;&lt;/button&gt;
  </code></pre>
  
  <p>For some reason, I'd like not to use the <code>class</code> attribute.</p>
