定义 dom,容器中包含一组 3 个面:
<div class="brick">
    <div class="sides">
        <span class='front'></span>
        <span class='right'></span>
        <span class="top"></span>
    </div>
</div>居中显示:
body {
    margin: 0;
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    background: radial-gradient(circle at center, white, skyblue);
}定义容器尺寸:
.brick {
    width: 40em;
    height: 30em;
    font-size: 10px;
}画出积木的正面:
.brick {
    position: relative;
}
.sides .front {
    position: absolute;
    width: 9em;
    height: 6.8em;
    background-color: #237fbd;
    top: 19em;
    left: 7em;
}画出积木的右面:
.sides > * {
    position: absolute;
    background-color: #237fbd;
}
.sides .right {
    width: 18em;
    height: 6.8em;
    filter: brightness(0.8);
    top: 19em;
    left: calc(7em + 9em);
}画出积木的顶面:
.sides .top {
    width: 18em;
    height: 10.4em;
    filter: brightness(1.2);
    top: calc(19em - 10.4em);
    left: calc(7em + 9em);
}把以上 3 个面组合成立方体:
.sides .front {
    transform-origin: right;
    transform: skewY(30deg);
}
.sides .right {
    transform-origin: left;
    transform: skewY(-30deg);
}
.sides .top {
    transform-origin: left bottom;
    transform: rotate(-60deg) skewY(30deg);
}接下来画积木的凸粒。
在 dom 中增加 8 个凸粒元素:
<div class="brick">
    <div class="sides">
        <span class='front'></span>
        <span class='right'></span>
        <span class="top"></span>
    </div>
    <div class="studs">
        <span></span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
        <span></span>
    </div>
</div>定义变量:
.studs span:nth-child(1) {
    --n: 1;
}
.studs span:nth-child(3) {
    --n: 3;
}
.studs span:nth-child(5) {
    --n: 5;
}
.studs span:nth-child(7) {
    --n: 7;
}
.studs span:nth-child(2) {
    --n: 2;
}
.studs span:nth-child(4) {
    --n: 4;
}
.studs span:nth-child(6) {
    --n: 6;
}
.studs span:nth-child(8) {
    --n: 8;
}画出左侧的凸粒:
.studs span:nth-child(odd) {
    top: calc(4.6em + (var(--n) - 1) / 2 * 2.6em);
    left: calc(23.3em - (var(--n) - 1) / 2 * 4.6em);
}画出右侧的凸粒:
.studs span:nth-child(even) {
    top: calc(6.9em + (var(--n) - 2) / 2 * 2.6em);
    left: calc(27.9em - (var(--n) - 2) / 2 * 4.6em);
}最后,画出凸粒的顶面:
.studs span::before {
    content: '';
    position: absolute;
    width: inherit;
    height: 2em;
    background-color: #4cb7ff;
    border-radius: 50%;
