title: Can I apply more than one CSS3 class to an element?
body: <p>I'm reading different opinions on this. Is this allowed in <s>CSS</s> HTML5:</p>
  
  <p><code>&lt;div class="one-class another-class"&gt;...</code></p>
  
  <p>to apply the properties of both <code>one-class</code> and <code>another-class</code> to the element?</p>

  <p><em>Re the downvote: yes, I tried it, and it does work. But that doesn't mean it's good practice. It could be deprecated for instance.</em></p>
