當然效果並不僅限於標題中的介紹，比如文字還具有凸起效果，裡面應用了css3屬性。

程式碼例項如下:

$(function () {

  var centerPoint = {
    centerX: $('.stage').width() / 2,
    centerY: $('.stage').height() / 2
  }
  $('.stage').on('mousemove', function (e) {
    var yDeg = (centerPoint.centerX - e.offsetX) * totalDeg / 90;
    var xDeg = -(centerPoint.centerY - e.offsetY) * totalDeg / 90;
    $(this).find('.card').css({
      '-webkit-transform': ' rotateX(' + xDeg + 'deg) rotateY(' + yDeg + 'deg)'
    })
  })
  $('.stage').on('mouseleave', function (e) {
    $(this).find('.card').removeAttr('style');
  })
