<h1>CSS Tombola</h1>

<p>First attempt to build and animate 3D shapes - hover to spin the tombola</p>

<div class="wrapper">
  <div class="tombola">
    <div class="panel p1">One</div>
    <div class="panel p2">Two</div>
    <div class="panel p3">Three</div>
    <div class="panel p4">Four</div>
    <div class="panel p5">Five</div>
    <div class="panel p6">Six</div>
    <div class="panel p7">Seven</div>
    <div class="panel p8">Eight</div>
  </div>
</div>


<p>The main sticking point was realising that translateZ() happens <em>after</em> the rotation of the panels. Also getting the tombola to rotate around the 'center' point using the 'Z' attribute of the transform-origin property</p>
<p><b>To-do:</b> Some sort of 'lighting' effect.</p>

script.js

// Script to randomise the panel the tombola lands on

$('.tombola').mouseenter(function(){
  var rotation = [1440,1485,1530,1575,1620,1665,1710,1755];
  var pick = Math.floor(Math.random()*8);
  var spin = rotation[pick];
 $('.tombola').css({'transform':'rotateX('+spin+'deg) translateZ(-480px)'});
});

$('.tombola').mouseleave(function(){
  $('.tombola').css({'transform':'rotateX(0deg) translateZ(-480px)'});
});
