代码解读
定义 dom,只有一个元素:
<div class="panda"></div>
居中显示:
body { margin: 0; height: 100vh; display: flex; align-items: center; justify-content: center; background-color: mediumturquoise; }
定义容器尺寸:
.panda { width: 21em; height: 16em; background-color: white; }
画出头部轮廓:
.panda { border: 0.5em solid #333; border-top-left-radius: 11em; border-top-right-radius: 11em; border-bottom-left-radius: 11em 6em; border-bottom-right-radius: 11em 6em; }
画出右眼轮廓:
.panda { position: relative; } .panda::before { content: ''; position: absolute; width: 7em; height: 4em; left: 2.9em; top: 5.5em; background-color: #333; border-radius: 50% 50% 45% 42%; transform: rotate(-45deg); }
类似地,画出左眼轮廓:
.panda::after { content: ''; position: absolute; width: 7em; height: 4em; left: 11.1em; top: 5.5em; background-color: #333; border-radius: 50% 50% 42% 45%; transform: rotate(45deg); }
画出两只耳朵:
.panda::before { box-shadow: 1em -7.2em 0 -0.4em #333; } .panda::after { box-shadow: -1em -7.2em 0 -0.4em #333; }
画出两只眼睛:
.panda::before { background-image: radial-gradient(circle at 5.1em 2em, white 0.3em, transparent 0.3em), radial-gradient(circle at 4.6em 2em, #333 0.7em, transparent 0.7em), radial-gradient(circle at 4.5em 2em, white 1em, transparent 1em); }.panda::after { background-image: radial-gradient(circle at 2.4em 1.5em, white 0.3em, transparent 0.3em), radial-gradient(circle at 2.4em 2em, #333 0.7em, transparent 0.7em), radial-gradient(circle at 2.5em 2em, white 1em, transparent 1em); }
画出鼻子和嘴:
.panda { background-image: radial-gradient(ellipse at 50% 60%, #333 1.2em, transparent 1.2em), radial-gradient(ellipse at 50% 80%, #555 0.6em, transparent 0.6em); }
增加一点立体效果:
.panda { border-bottom-width: 1em; box-shadow: inset 1em -1em 0 #eee; }
让右眼动起来:
.panda::before { animation: before-animate 1s ease-in-out infinite alternate; } @keyframes before-animate { to { background-image: radial-gradient(circle at 4.9em 1.8em, white 0.3em, transparent 0.3em), radial-gradient(circle at 4.4em 1.8em, #333 0.7em, transparent 0.7em), radial-gradient(circle at 4.5em 2em, white 1em, transparent 1em); } }
类似地,让左眼也动起来:
.panda::after { animation: after-animate 1s ease-in-out infinite alternate -1s; } @keyframes after-animate { to { background-image: radial-gradient(circle at 2.6em 1.3em, white 0.3em, transparent 0.3em), radial-gradient(circle at 2.6em 1.8em, #333 0.7em, transparent 0.7em), radial-gradient(circle at 2.5em 2em, white 1em, transparent 1em); } }
最后,让黑眼圈和耳朵也动起来:
@keyframes before-animate { to { transform: rotate(-40deg); } } @keyframes after-animate { to { transform: rotate(40deg); } }
大功告成!
