The implementation code is as follows. The comments in the code are already quite detailed, so 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: &#39;&#39;;
        }
        /* 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>
</head>
<body>
    <section class="container">
        <p class="content" title="新年好新年好新年好">
            <p class="con-text">新年好新年好新年好</p>
        </p>
