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!
