前言: 前两天写了一下关于flex布局的相关知识的回顾,今天就用flex和动画做一个旋转的骰子吧,单独写一个六点的骰子有点单调,加上动画效果就好看多了.至于点数有没有一一对应哪个面我就没整,放到哪个面就是哪个面了.

小点

首先把骰子的小点写出来,后面直接用就可以了

.active {
      width: 50px;
      height: 50px;
      border-radius: 25px;
      background-color: red;
    }

一点

一点肯定是最好写的啦,用flex然后主轴和侧轴都居中就可以了.代码如下

<style>
.front {
      display: flex;
      justify-content: center;
      align-items: center;
      transform: translateZ(200px);
    }
</style>   
<body>
 <div class="front">
      <div class="active"></div>
    </div>
 </body>

二点

二点跟一点一样,侧轴仍然是居中,不同的地方在于,有两个点,然后主轴是space-evenly.代码如下

<style>
.back {
      display: flex;
      align-items: center;
      justify-content: space-evenly;
    }
</style>
<body>
<div class="back">
      <div class="active"></div>
      <div class="active"></div>
    </div>
</body>

三点

三点我是用了三个盒子,然后把点分别放在三个盒子里.三个盒子将平面分成三等分.第一个点是从头排列,第二个点是居中排列,第三个点是从末尾开始排列.代码如下

<style>
.left>div {
      display: flex;
      width: 100%;
      height: 33.33%;
    }

    .left .box1 {
      justify-content: start;
      padding: 8px;
    }

    .left .box2 {
      justify-content: center;
    }

    .left .box3 {
      justify-content: end;
      padding: 8px;
    }
</style>
<body>
<div class="left">
      <div class="box1">
        <div class="active"></div>
      </div>
      <div class="box2">
        <div class="active"></div>
      </div>
      <div class="box3">
        <div class="active"></div>
      </div>
    </div>
</body>

四点

四点用了两个标准流的盒子,里面分别装两个小点.主轴小点间间距相等,侧轴直接居中就可以了.

<style>
 .right .box {
      display: flex;
      justify-content: space-evenly;
      align-items: center;
      width: 100%;
      height: 50%;
    }
</style>
<body>
<div class="right">
      <div class="box">
        <div class="active"></div>
        <div class="active"></div>
      </div>
      <div class="box">
        <div class="active"></div>
        <div class="active"></div>
      </div>
    </div>
</body>

五点

五点用三个标准流的盒子,上下两个点跟二点的做法一样,中间的点跟一点的做法类似.

<style>
.top>div {
      display: flex;
      width: 100%;
      height: 33.33%;
    }

    .top .box1 {
      justify-content: space-evenly;
      align-items: center;
    }

    .top .box2 {
      justify-content: center;
      align-items: center;
    }

    .top .box3 {
      justify-content: space-evenly;
      align-items: center;
    }
</style>
<body>
<div class="top">
      <div class="box1">
        <div class="active"></div>
        <div class="active"></div>
      </div>
      <div class="box2">
        <div class="active"></div>
      </div>
      <div class="box3">
        <div class="active"></div>
        <div class="active"></div>
      </div>
    </div>
</body>

六点

六点用三个标准流的盒子,然后里面放两个点.做法跟二点一样.

<style>
.bottom>div {
      display: flex;
      justify-content: space-evenly;
      align-items: center;
      width: 100%;
      height: 33.33%;
    }
</style>

<body>
<div class="bottom">
      <div>
        <div class="active"></div>
        <div class="active"></div>
      </div>
      <div>
        <div class="active"></div>
        <div class="active"></div>
      </div>
      <div>
        <div class="active"></div>
        <div class="active"></div>
      </div>
    </div>
</body>

叨叨半天,写完了,下面是完整的代码和效果图,效果图是可以转起来,就截图了一个转了一半的图.
