title: Calculating square-roots with CSS
body: <p>Is it possible to do a square-root function in the calc() function of my CSS file? I've read that calc() only supports the basic operators like + - * and /.</p>
  
  <p>Ideally, it'd look something like this:</p>
  
  <pre><code>width: calc(50% - (sqrt(7200))px);
  </code></pre>
  
  <p>If calc() do not have a sqrt function, what can I do?</p>
