Background: Because I saw that many pages have the effect as shown below, click on the red line frame part, and the page will slide to another position. Looking at the source code of the page, I found that the red line frame part is a CSS rounded border. Implemented, so...

Upload the code

<!DOCTYPE html><html><head lang="en">    <meta charset="UTF-8">    <title></title>    <link rel="stylesheet" href="css/bootstrap.min.css" type="text/css"/>    <style>        body{            margin:0px;            padding:0px;            background-color: #1f272a;        }        /*圆角效果的实现*/        .btn-dwn {            /*            必填项            */            /*宽度和高度必须一致，才能保证是圆形*/            width: 58px;            height: 58px;            /*border-radius的属性值越大，圆形效果越明显*/            border-radius: 50%;            /*设置边框大小、样式、颜色*/            border: 2px solid rgba(255,255,255,.15);            /*            非必填项            */            color: rgba(255,255,255,.6);            text-align: center;            font-size: 18px;            position: absolute;            left: 50%;            bottom: 60px;            line-height: 58px;        }    </style>    <script>        //滑动效果        function scrollToTarget(D){            if(D == 1) // Top of page            {                D = 0;            }            else if(D == 2) // Bottom of page            {                D = $(document).height();            }            else // Specific Bloc            {                D = $(D).offset().top;            }            $('html,body').animate({scrollTop:D}, 'slow');        }    </script></head><body><a onclick="scrollToTarget('#core')" class="btn-dwn"><span class="glyphicon glyphicon-chevron-down"></span></a></body></html>

Achieve the effect
