The implementation code is as follows, and the comments in the code are quite detailed. , I won’t say more:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
body {
width: 40rem;
height: 30rem;
font-size: 62.50%; /* 把body的字体设置为10px以方便使用rem时的计算 */
}
.container {
width: 100%;
height: 100%;
background: #0f0;
text-align: center;
}
/* 设置content元素的属性 */
/* 此元素的宽和高必须相等，即设置border-radius: 50%;后应该是一个圆 */
/* 使用rem相对于body的字体尺寸设置了宽和高 */
.content {
display: inline-block;
margin-top: 5rem;
width: 20rem;
height: 20rem;
border: solid 15px rgba(255, 255, 255, 1); /* 此处设置边框，使用rgba的方式是为了后面隐藏时方便，只需要设置a的值为0即可隐藏 */
border-radius: 50%;
box-sizing: border-box; /* 使用此属性防止边框撑开盒子，border-box会让边框占用盒子里面的空间 */
transition: all 2s; /* 该元素的所有属性的变化会在2s内完成 */
}
/* 使用伪类before设置需要转动的边框 */
/* 因为如果元素边框转动，内容也会跟着转动 */
/* 此处要的效果是只有边框转动而内容不转动 */
.content:before {
display: inline-block;
width: 100%;
height: 100%;
border-radius: 50%;
box-sizing: border-box;
content: '';
}
/* 设置鼠标悬停在content元素上时content属性的变化 */
.content:hover {
/*border: solid 15px rgba(255, 255, 255, 0);*/
}
/* 设置鼠标悬停在content上时content的before伪类属性的变化 */
.content:hover:before {
border: dashed 30px #fff;
animation: whirl 9s linear infinite; /* 执行动画whirl,执行一次的周期是9s,执行期间的速度曲线为linear,无限循环 */
}
/* 设置文本内容显示的样式 */
.con-text {
margin: -60% auto;
width: 80%;
font-size: 3rem;
/* 以下三个属性为了让文字超出宽度时显示省略号，必须同时使用才有效果 */
overflow: hidden;
white-space: nowrap;
text-overflow: ellipsis;
}
/* 动画whirl,从0度旋转到360度 */
@keyframes whirl {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
</style>
