默认情况下为正方形，也许小伙伴觉得不太好看。我们换成圆形的试试！

            height: 100px;
            border-radius: 50%;
            background-color: rgb(28, 99, 60);
            border: 5px solid rgb(55, 0, 255);
            position: absolute;
            margin: 0 auto;
            left: 0;
            right: 0;
            bottom: 0;
            top: 0;
        }
    </style>

看一下我们变成了圆形！来看看半圆形的吧！

            background-color: rgb(175, 42, 216);
            border: 3px solid rgb(26, 236, 26);
            border-top-right-radius: 50px;
            border-top-left-radius: 50px;
            position:absolute;
            margin: 0 auto;
            left: 0;
            right: 0;
            bottom: 0;
            top: 0;
