title: Using modulus in css calc function
body: <p>Is there any way to use or implement modulus operator in css calc function?<br>
  I know there is mod operator and IE supports it, but what about other browsers?  </p>
  
  <p>For example</p>
  
  <pre><code>#element-id{
       width: calc( 100%  mod 5 );
  }
  </code></pre>
