定义 dom,容器中包含 3 个元素,分别代表头、身体和脚:
<div class="man">
<span class="head"></span>
<span class="body"></span>
<span class="feet"></span>
</div>居中显示:
body {
margin: 0;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;
background: radial-gradient(lightgray 20%, whitesmoke);
}定义容器尺寸:
.man {
width: 12em;
height: 33em;
font-size: 10px;
position: relative;
}定义主色:
.man {
color: white;
}画出头部:
.head {
position: absolute;
width: 7em;
height: 7em;
background-color: currentColor;
border-radius: 50%;
right: 0;
}画出身体:
.body {
position: absolute;
width: 6.2em;
height: 14.4em;
background-color: currentColor;
top: 7em;
border-radius: 100% 20% 0 0;
}画出脚,现在只能看到一只脚,是因为两只脚重叠在一起,一会儿动起来时就能看到两只脚了:
.feet::before,
.feet::after {
content: '';
position: absolute;
width: 4em;
height: 1.4em;
background-color: white;
bottom: 0;
left: -1.6em;
border-radius: 1em 80% 0.4em 0.4em;
}用伪元素画出阴影:
.man::before {
content: '';
position: absolute;
width: 12em;
height: 0.8em;
background-color: rgba(0, 0, 0, 0.1);
bottom: -0.2em;
left: -3em;
border-radius: 50%;
}接下来增加动画效果。
增加行走的动画效果,并使两只脚的动画时间交错:
.feet::before,
.feet::after {
animation: feet-animation 2s ease-in-out infinite;
}
.feet::after {
animation-delay: 1s;
}
@keyframes feet-animation {
20% {
transform: translateX(3.4em) translateY(-1.6em) rotate(4deg);
}
30% {
transform: translateX(4.6em) translateY(-1em) rotate(0deg);
}
40% {
transform: translateX(5.6em) translateY(-0.6em) rotate(4deg);
}
44% {
transform: translateX(5.6em) translateY(0) rotate(0deg);
}
}增加头和身体起伏的动画效果:
.head,
.body {
animation: body-animation 4s ease-in-out infinite;
}
@keyframes body-animation {
0%, 100% {
transform: translateY(0) skewX(-2deg);
}
25%, 75% {
transform: translateY(0.5em) skewX(0deg);
}
50% {
transform: translateY(0) skewX(0deg);
}
}增加阴影面积随身体运动而变化的动画效果:
.man::before {
animation: shadow-animate 4s ease-in-out infinite;
}
@keyframes shadow-animate {
0%, 50%, 100% {
transform: scale(1);
}
25%, 75% {
transform: scale(1.15);
}
}大功告成!
