     2、参考：http://iwenku.net/?article_167.html

    body {
                scroll-behavior: smooth;
            }
            .catalog {
                position: fixed;
                top: 27%;
                left: 82%;
                z-index: 11;

                box-shadow:0 0px 0px rgba(0,0,0,0.5);
                border-radius: 10%;

                padding: 10px;
                
                transform: rotate(0deg);
                transition: 0.5s ease-in-out;
            }
            
            .catalog:hover {
                box-shadow:0 10px 20px rgba(0,0,0,0.5);
                
                transform: rotate(0deg);
                transition: 0.6s ease-in-out;
            }

    scroll-behavior只有少数浏览器支持，

    顺便记一下自己写的一个索引样式。。。

    js权限没申请成功，css弄了半天也没实现，心累，就这样吧。。。

    update：

    申请成功了...

    j继续弄，参考：https://blog.brain1981.com/410.html
