思路：骰子有6个面，那么创建6个div为6个面，然后用css3的旋转属性旋转每个面到相应位置，每个面里面的点使用绝对定位确实位置。骰子旋转写一个动画改变rotate值。

用js控制旋转结果：

 //动画配置开始
    let diceWrap = document.querySelector('.diceWrap');
    //不同开奖号码的配置,不同数字代表不同开奖结果
    let keyframes = {
        '1': [{
            transform: 'rotate3d(1, 1, 1, 0deg) rotateX(-270deg) scale3d(1, 1, 1)'
        }, {
            transform: 'rotate3d(1, 1, 1, 360deg) rotateX(90deg) scale3d(1, 1, 1)'
        }],
        '2': [{
            transform: 'rotate3d(1, 1, 1, 0deg) rotateX(-90deg) scale3d(1, 1, 1)'
        }, {
            transform: 'rotate3d(1, 1, 1, 360deg) rotateX(270deg) scale3d(1, 1, 1)'
        }],
        '3': [{
            transform: 'rotate3d(1, 1, 1, 0deg) rotateY(0deg) scale3d(1, 1, 1)'

        }],
        '5': [{
            transform: 'rotate3d(1, 1, 1, 0deg) rotateZ(-90deg) scale3d(1, 1, 1)'

    }
    let animationConfig = {

        iterations: 10,
        fill: 'forwards', //当动画完成后，保持最后一个属性值（在最后一个关键帧中定义）
    };
    //动画配置结束

    function roll(number) {
