代码解读

定义 dom,容器中包含的几个元素分别代表头部、眼睛、嘴、身体和腿:

<div class="buddha">
    <div class="head"></div>
    <div class="eyes"></div>
    <span class="mouth"></span>
    <span class="body"></span>
    <span class="legs"></span>
    <span class="shadow"></span>
</div>

居中显示:

body {
    margin: 0;
    height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    background: linear-gradient(white, bisque);
}

定义容器尺寸、设置子元素水平居中对齐:

.buddha {
    width: 13em;
    height: 19em;
    font-size: 20px;
    border: 1px dashed black;
    display: flex;
    align-items: center;
    flex-direction: column;
    position: relative;
}

画出头部轮廓:

.head {
    width: 12.5em;
    height: 12.5em;
    color: peachpuff;
    background: currentColor;
    border-radius: 50%;
    filter: brightness(0.9);
}

用伪元素画出眼睛:

.eyes::before,
.eyes::after {
    content: '';
    position: absolute;
    width: 1em;
    height: 0.5em;
    border: 0.6em solid #333;
    border-radius: 1em 1em 0 0;
    border-bottom: none;
    top: 6em;
}

.eyes::before {
    left: 2.5em;
}

.eyes::after {
    right: 2.5em;
}

画出嘴巴:

.mouth {
    position: absolute;
    width: 1.5em;
    height: 0.5em;
    border: 0.5em solid tomato;
    border-radius: 0 0 1.5em 1.5em;
    border-top: none;
    top: 9em;
}

画出身体:

.body {
    position: absolute;
    width: 10em;
    height: 8em;
    background-color: coral;
    border-radius: 4em;
    bottom: 1em;
    z-index: -1;
}

画出腿:

.legs {
    position: absolute;
    width: inherit;
    height: 5em;
    background-color: coral;
    border-radius: 2.5em;
    bottom: 0;
    z-index: -1;
}

用阴影画出耳朵和手:

.head {
    box-shadow: 
        5.8em 2em 0 -4.8em, /* ear right*/
        -5.8em 2em 0 -4.8em, /* ear left*/
        0 8.6em 0 -4.5em; /* hand */
}

用径向渐变画出眉心:

.head {
    background: 
        radial-gradient(
            circle at 50% 40%,
            tomato 0.6em,
            transparent 0.6em
        ), /* circle between eyebrows */
        currentColor;
}

画出身体的阴影:

.shadow {
    position: absolute;
    width: inherit;
    height: 5em;
    background-color: rgba(0, 0, 0, 0.2);
    border-radius: 50%;
    bottom: -4em;
    transform: rotateX(100deg);
}

让小和尚上下浮动:

.buddha {
    animation: animate 3s ease-in-out infinite;
}

@keyframes animate {
    50% {
        transform: translateY(-2em);
    }
}

让阴影保持在固定位置,不随着人浮动:

.shadow {
    animation: shadow-animate 3s ease-in-out infinite;
}

@keyframes shadow-animate {
    50% {
        transform: rotateX(100deg) translateY(-10em) scale(0.7);
    }
}

大功告成!
