    * {
        padding: 0;
        margin: 0;
    }
    html,
    body {
         100%;
        height: 100%;
        overflow: hidden;
        background-color: rgb(0,0,0);
    }
    .eat-wrap {
         200px;
        height: 200px;
        margin-top: 100px;
        background-color:  rgb(0,0,0);
        border-radius: 50%;
        box-shadow:
            250px 0px 0px -80px red,
            350px 0px 0px -80px red,
            450px 0px 0px -80px red,
            550px 0px 0px -80px red;
        animation: eaty-move 1s infinite;
    }
    .eat-wrap::before {
        content: '';
         200px;
        height: 100px;
        display: block;
        margin-left:80px;
        border-radius: 100px 100px 0px 0px;
        background-color: peru;
        transform: rotate(-20deg);
        /* infinite 无限循环 */
        animation: eaty-top 1s infinite;
    }
    .eat-wrap::after {
        content: '';
         200px;
        height: 100px;
        margin-left: 80px;
        display: block;
        border-radius: 0px 0px 100px 100px;
        background-color: peru;
        /* 变化:角度rotate(20deg) */
        transform: rotate(20deg);
        animation: eaty-bot 1s infinite;
    }

  //文字立体效果

    h2 {
        font-size:104px;
        color: purple;
        margin-left: 50px;
        /* x,y,阴影距离,颜色 */

    }
    @keyframes eaty-top {
        0% {
            transform: rotate(-0deg);
        }
        50% {
            transform: rotate(-20deg);
        }

        }
    }

//吃豆豆动画

    @keyframes eaty-move {
