css3骰子(transform初识)

利用css3制作可旋转的骰子,效果图如下,也可以查看 demo

首先是骰子的html结构,.page 是骰子的六个页面的 class,#one-#six分别表示六个面,.point 是骰子表面的点数:

  <div id="diceWapper">
        <div id="dice">
            <div id="one" class="page">
                <div class="point first"></div>
            </div>
            ...
        </div>        
    </div>

接着是控制骰子旋转方向和度数的控制器:

  <div id="controler">
        <div class="direction">
            <span class="way">X 方向:<span id="xValue">0</span></span><input type="range" id="rotateX" min="-360" max="360" value="0" onchange="rotate()" />
        </div>
        ...
    </div>

通过css设置骰子各个面的位置,

首先设置 3d 场景:-webkit-perspective: 800; -webkit-perspective-origin: 50% 50%; 场景离显示器距离 800,观察位置在显示器中间,

再设置 transform-style 转换类型为 3d 转换,

然后通过 position 来设置各个表面以及表面上点的位置,

最后用 transform-origin 给各个表面设置旋转轴的位置,和用 rotateX、rotateY、rotateZ 设置旋转角度:

  #diceWapper{
        -webkit-perspective: 800;
        -webkit-perspective-origin: 50% 50%;
    }

    #dice{
        position: relative;
        -webkit-transform-style:preserve-3d;
    }

    .page{
        -webkit-transition: -webkit-transform 1s linear;
        position:absolute;
    }

    #two {
        -webkit-transform-origin:right;
        -webkit-transform: rotateY(-90deg);
    }
  ...

最后就是通过 input:range 的 change 事件来控制不同方向的旋转角度,获取三个 range 的 value 来设置 #dice 的 webkitTransform 实现转动。

完整代码如下(可运行):
