    Written casually without considering compatibility. You can change the movement speed or something by yourself

        <style>
            #app{
                width: 300px;
                height:400px;
                border: 1px solid #d6e9c6;
                position: relative;
            }
            .barTip{
                width: 100px;
                height: 10px;
                background: red;
                position: absolute;
                top: 130px;
                left: 32%;
            }
            #bar{
                position: absolute;
                width: 30px;
                height:30px;
                background: #2a6496;
                border-radius: 15px;
                left: 45%;
                animation-name:myfirst;
                animation-duration:2s;
                animation-timing-function:linear;

                animation-direction:alternate;
                animation-play-state:running;
            }
            @keyframes myfirst
            {
                0%   { top:0px;}
                10%  { top:20px;}

                80%  { top:40px;}
                90% { top:20px;}
                100% { top:0px;}
            }
        </style>
    </head>
