title: How to force only numbers in a input, without Javascript?
body: <p><strong>CodePen: <a href="http://codepen.io/leongaban/pen/hbHsk" rel="nofollow noreferrer">http://codepen.io/leongaban/pen/hbHsk</a></strong></p>
  
  <p>I've found multiple answers to this question on stack <a href="https://stackoverflow.com/questions/12533508/only-allow-numbers-in-input-tage-without-javascript">here</a> and <a href="https://stackoverflow.com/questions/773843/iphone-uiwebview-how-to-force-a-numeric-keyboard-is-it-possible">here</a></p>
  
  <p>However they all suggest the same fix, using <code>type="number"</code> or <code>type="tel"</code></p>
  
  <p>None of these are working in my codepen or project :(</p>

  <p>Do you see what I'm missing?</p>
