title: Force leading zero in number input
body: <p>I'm writing an alarm web app. I have two number inputs, one for the hours, one for the minutes. Thus, when I use my keyboard arrows, they go from 0 to 23/59. Is there an HTML native way to make them go from 00 (01,02, et.) to 23/59 instead ?</p>
  
  <p>I'm only worried about the UI aspects as my JS manages the missing 0 anyway.</p>
  
  <p>EDIT - As requested :</p>
  
  <p>What I have :</p>

  <p>Instead of going from 0,1,2 to 59, I'd like to automatically have a leading 0 when the number is smaller than 10 (00,01,02 to 59).</p>
