原文链接感謝 comehope 大佬的 [前端每日实战]
工作三个月觉得糟糕跑路(顺带劝一下像我一样的新人, 不要急于入职, 一定要挑一挑)回家重新补充了一下基础知识及 node, 身为一个前端结果发现 CSS 已经手生了, 为了明年能够找到工作, 所以又开始练习了...

html 结构我们需要五颗爱心及底部的 footer
<figure class="hearts">
<section class="heart"></section>
<section class="heart"></section>
<section class="heart"></section>
<section class="heart"></section>
<section class="heart"></section>
</figure>
<footer>pink hearts</footer>样式初始化及居中
body {
margin: 0;
height: 100vh;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
background-color: #f3f3f3;
overflow: hidden;
}
.hearts {
width: 100vw;
height: 20vw;
border: 1px solid; /* the snippet will be deleted */
box-sizing: border-box;
padding: 0 5vw;
display: flex;
align-items: center;
justify-content: space-between;
}
.heart {
width: 15vw;
height: 15vw;
border: 1px solid; /* the snippet will be deleted */
}
footer {
margin-top: 10vh;
text-transform: uppercase;
letter-spacing: 2px;
font-family: "verdana";
font-size: 22px;
color: #F48FB1;
}接着在第一个 heart 中添加一个粉红的正方形
添加 DOM 结构
<section class="heart">
<div class="plane">
<div class="half-heart"></div>
</div>
</section>基准面(plane) 定位并完成基础样式
.heart {
position: relative;
display: flex;
align-items: center;
justify-content: center;
}
.plane {
position: absolute;
opacity:0.8;
}
.half-heart {
width: 7.5vw;
height: 7.5vw;
background-color: pink;
transform: rotate(-45deg);
}一颗爱心由两个基准面组成
<section class="heart">
<div class="plane plane-left">
<div class="half-heart"></div>
</div>
<div class="plane plane-right">
<div class="half-heart"></div>
</div>
</section>.heart {
transform-style: preserve-3d;
}
.plane-right {
transform: rotateY(90deg); /* 因为此处为 90 度垂直, 所以并不可见 */
}接着添加旋转动画(这样我们就可以看到两个基准面了)
.heart {
animation: rotate 5s ease-in-out infinite;
}
.heart:nth-of-type(1) {
animation-delay:-5s;
}
/* keyframes */
@keyframes rotate {
0% {
transform: rotateY(0deg) rotateZ(25deg) translateY(7.5vw);
}
50% {
transform: rotateY(270deg) rotateZ(25deg) translateY(-7.5vw);
}
100% {
transform: rotateY(360deg) rotateZ(25deg) translateY(7.5vw);
}
}生成两个圆形放置在正方的上方即可(伪元素可解决)
.half-heart:before,
.half-heart:after {
content: "";
width: 7.5vw;
height: 7.5vw;
background-color: pink;
border-radius: 100%;
position: absolute;
}
.half-heart:before {
top: -3.25vw;
left: 0;
}
.half-heart:after {
top: 0;
left: 3.25vw;
}好了, 这样一个旋转上升的爱心就完成了
修改延迟时间(DOM 结构省略)
.heart:nth-of-type(1) {
animation-delay:-5s;
}
.heart:nth-of-type(2) {
animation-delay:-4s;
}
.heart:nth-of-type(3) {
animation-delay:-3s;
}
.heart:nth-of-type(4) {
animation-delay:-2s;
}
.heart:nth-of-type(5) {
animation-delay:-1s;
}最后记得把之前确认位置及大小的 border 边框删除即可
