## 代码解读 ##

定义 dom，容器中包含 2 个元素：

居中显示：

body {
        margin: 0;
        height: 100vh;
        display: flex;
        align-items: center;
        justify-content: center;
        background-color: darkslategray;
    }

绘制出冰棍的外形：

.flavors {
        width: 19em;
        height: 26em;
        font-size: 10px;
        border-radius: 8em 8em 1em 1em;
    }

给冰棍上色：

.flavors {
        position: relative;
        overflow: hidden;
    }
    
    .flavors::before {
        content: '';
        position: absolute;
        width: 140%;
        height: 120%;
        background: linear-gradient(
            hotpink 0%,
            hotpink 25%,
            deepskyblue 25%,
            deepskyblue 50%,
            gold 50%,
            gold 75%,
            lightgreen 75%,
            lightgreen 100%);
        z-index: -1;
        left: -20%;
        transform: rotate(-25deg);
    }

来一点光照效果：

.flavors::after {
        content: '';
        position: absolute;
        width: 2em;
        height: 17em;
        background-color: rgba(255, 255, 255, 0.5);
        left: 2em;
        bottom: 2em;
        border-radius: 1em;
    }

画出冰棍筷子：

.stick {
        position: relative;
        width: 6em;
        height: 8em;
        background-color: sandybrown;
        left: calc(50% - 6em / 2);
        border-radius: 0 0 3em 3em;
    }

给冰棍筷子加一点阴影，增加立体感：

.stick::after {
        content: '';
        position: absolute;
        width: inherit;
        height: 2.5em;
        background-color: sienna;
    }

让冰棍的色彩滚动起来：

.flavors::before {
        animation: moving 100s linear infinite;
    }
    
    @keyframes moving {
        to {
            background-position: 0 1000vh;
        }
    }

最后，增加交互效果，当鼠标悬停时才播放动画：

.flavors::before {
        animation-play-state: paused;
    }
    
    .ice-lolly:hover .flavors::before {
        animation-play-state: running;
    }

大功告成！
