html样式

一、二、三这三个点数很容易，div里面有几个点就加几个span。到了四，就需要进行分组。四分两组，五和六分三组

<div>
    <span></span>
</div>
<div>
    <span></span><span></span>
</div>
<div>
    <span></span>
    <span></span>
    <span></span>
</div>
<div>
    <article><span></span><span></span></article>
    <article><span></span><span></span></article>       
</div>
<div>
    <article><span></span><span></span></article>
    <article><span></span></article>
    <article><span></span><span></span></article>
</div>
<div>
    <article>
        <span></span>
        <span></span>
    </article>
    <article>
        <span></span>
        <span></span>
    </article>
    <article>
        <span></span>
        <span></span>
    </article>
</div>

css代码

先写容器骰子的样式

    body{
        display: flex;
        justify-content: space-around;
        align-items: center;
    }
    div{
        width: 100px;
        height: 100px;
        background: #e7e7e7;
        padding: 4px;
        box-shadow: inset 0 5px white, inset 0 -5px #bbb, inset 5px 0         #d7d7d7, inset -5px 0 #d7d7d7;
         border-radius: 10px;
        }

接下来写点数span的样式，写一、二、三点。##先把骰子的六个面在游览器水平居中排列:六个div，给它们设置相同的样式。同时body要把它转换成弹性盒。让六个div在body弹性盒中，沿着主轴（x轴）自由分配，同时在侧轴（y轴）居中。

    span{
        width: 30px;
        height: 30px;
        background: #000;
        border-radius: 15px;
    }
    div:nth-child(1){
        display: flex;
        justify-content: center;
        align-items: center;
    }
    div:nth-child(2){
        display: flex;
        justify-content: space-between;
    }
    div:nth-child(2) span:nth-child(2){
        
        align-self: flex-end;
    }
    div:nth-child(3){
        display: flex;
        justify-content: space-between;
    }
    div:nth-child(3) span:nth-child(2){
        align-self: center;
    }
    div:nth-child(3) span:nth-child(3){
        align-self: flex-end;
    }

第四点有两种写法。不论哪一种，article的样式都一样

article{
            display: flex;
            justify-content: space-between;
}

第一种

div:nth-child(4){
    display: flex;
    justify-content: space-between;
}
div:nth-child(4) article{
    display: flex;
    flex-direction: column;
    justify-content: space-between;
}

第二种

div:nth-child(4){
        display: flex;
        flex-direction: column;
        justify-content: space-between;
    }

五和六的代码

div:nth-child(5){
            display: flex;
            flex-direction: column; 
        }
        div:nth-child(5) article:nth-child(2){
            justify-content: center;
        }
        div:nth-child(6){
            display: flex;
            flex-direction: column;
        }

最后的效果如下图所示
