代码解读

定义 dom,容器中包含一个表示酒桶的 .keg 元素和表示啤酒杯的 .glass 元素。酒桶有 2 个子元素,.handle 表示把手,.pipe 表示出水管,酒杯有 1 个表示啤酒的子元素 .beer

<div class="container"> <div class="keg"> <span class="handle"></span> <span class="pipe"></span> </div> <div class="glass"> <span class="beer"></span> </div></div>

居中显示:

body { margin: 0; height: 100vh; display: flex; justify-content: center; background: linear-gradient( lightslategray 300px, #333 300px );}

定义容器尺寸和伪元素的共有属性:

.container { width: 700px; height: 300px; position: relative;}.container *::before,.container *::after { content: ''; position: absolute;}

画出酒桶:

.keg { position: absolute; width: 90px; height: 200px; background: linear-gradient( to right, #777 70px, #555 70px ); bottom: 0; left: 310px;}

画出出水管和它的支架:

.keg .pipe { position: absolute; width: 10px; height: 40px; background-color: #ccc; top: 33px; left: 10px;}.keg .pipe::before { width: 40px; height: 20px; background: radial-gradient( circle at 10px 10px, #eee 7px, #ccc 7px, #ccc 10px, transparent 10px ), linear-gradient( #ccc 50%, #999 50% ); border-radius: 10px; top: -2px; left: -5px;}

画出把手:

.keg .handle { position: absolute; border-style: solid; border-width: 50px 10px 0 10px; border-color: black transparent transparent transparent; top: -10px; left: 5px;}.keg .handle::before { width: 20px; height: 10px; background-color: #ccc; top: -60px; left: -10px; border-radius: 5px 5px 0 0;}.keg .handle::after { width: 10px; height: 20px; background-color: #ccc; top: -20px; left: -5px;}

画出酒杯:

.glass { position: absolute; width: 70px; height: 100px; color: rgba(255, 255, 255, 0.3); background-color: currentColor; bottom: 0; left: 300px; border-radius: 5px;}.glass::before { width: 50px; height: 40px; border: 10px solid; top: 20px; right: -20px; border-radius: 0 40% 40% 0; clip-path: inset(0 0 0 72%);}

画出杯中的啤酒和泡沫:

.beer { position: absolute; width: 60px; height: 80px; background-color: rgba(255, 206, 84, 0.8); bottom: 15px; left: 5px; border-radius: 0 0 5px 5px; border-top: solid rgba(255, 206, 84, 0.8);}.beer::before { width: inherit; height: 15px; background-color: #eee; top: -15px; border-radius: 5px 5px 0 0;}

接下来制作动画。

增加酒杯把手被压下的动画效果:

.keg .handle { transform-origin: center 50px; animation: handle 5s infinite;}@keyframes handle { 10%, 60% { transform: rotate(0deg); } 20%, 50% { transform: rotate(-90deg); }}

增加啤酒被斟满的动画效果:

.beer { animation: fillup 5s infinite;}@keyframes fillup { 0%, 20% { height: 0px; border-width: 0px; } 40% { height: 40px; } 80%, 100% { height: 80px; border-width: 5px; }}

增加啤酒泡沫泛起的动画效果:

.beer::before { animation: wave 0.5s infinite alternate, fillup-foam 5s linear infinite;}@keyframes fillup-foam { 0%, 20% { top: 0; height: 0; } 60%, 100% { top: -15px; height: 15px; }}@keyframes wave { from { transform: skewY(-3deg); } to { transform: skewY(3deg); }}

增加啤酒从出水口流出的效果:

.keg .pipe::after { width: 10px; background-color: rgba(255, 206, 84, 0.5); animation: flow 5s infinite;}@keyframes flow { 0%, 15% { top: 40px; height: 0; } 20% { height: 115px; } 40% { height: 75px; } 55% { top: 40px; height: 50px; } 60%, 100% { top: 80px; height: 0; }}

最后,增加酒杯滑动的效果:

.glass { animation: slide 5s ease infinite;}@keyframes slide { 0% { left: 0; filter: opacity(0); } 20%, 80% { left: 300px; filter: opacity(1); } 100% { left: 600px; filter: opacity(0); }}
