    [JQuery] Random Card Generator

    The following code will generate a random playing card. The possible values are 2, 3, 4, 5, 6, 7, 8 ,9 , 10, Jack, Queen, and King whereas the possible suits are spade, heart, club, and diamond. The CSS height/width dimensions for the card are taken from the standard card sizes, so if you were to hold up a real card to the screen the size should match up.

    HTML
    HTML Code:
    <div class="card">
      <div class="cardLeft">
        <h2></h2>
      </div>
      <div class="cardCenter">
        <h2></h2>
      </div>
      <div class="cardRight">
        <h2></h2>
      </div>
    </div>
    
    <input id="btnDraw" type="button" value="Draw" />
    CSS
    Code:
    .card {
      display: -ms-flexbox;
      display: -webkit-flex;

      $('#btnDraw').on('click', function() {
        var value = Math.floor(Math.random() * values.length);
        var suit = Math.floor(Math.random() * suits.length);
        
        $('.card h2').removeClass().addClass((suit < 2) ? 'redSuit' : 'blackSuit').children().remove();
        
        $('.cardLeft h2, .cardRight h2').text(values[value] + suits[suit]);
        $('.cardCenter h2').text(suits[suit]);
      });
