从B站上看到的小项目，炫酷又简单。

HTML模块：

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

<body>
    <div class="loader">
        <span></span>
        <span></span>
        <span></span>
        <h2>Loading...</h2>
    </div>
</body>

</html>

CSS模块：

* {
    /* 清除默认边距 */
    margin: 0;
    padding: 0;
    /* box-sizing: border-box;元素的总高度和宽度包含内边距和边框(padding 与 border) : */
    box-sizing: border-box;
}

body {
    /* display: flex; 弹性布局*/
    display: flex;
    /*justify-content: center;表示居中排列 */
    justify-content: center;
    /* 居中对齐弹性盒的各项 <div> 元素： */
    align-items: center;
    /* 设置背景颜色 */
    background-color: rgb(79, 80, 87);
    /* 设置段落的最小高度 */
    min-height: 100vh;
}

.loader {
    /* position的属性之一：relative（相对定位）：生成相对定位的元素，通过top,bottom,left,right的设置相对于其正常（原先本身）位置进行定位。可通过z-index进行层次分级。　　 */
    position: relative;
    width: 200px;
    height: 200px;
    display: flex;
    justify-content: center;
    align-items: center;
}

.loader span {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    /*  */
    border: 2px solid skyblue;
    pointer-events: none;
    /* 语法：animation: name duration timing-function delay iteration-count direction fill-mode play-state; */
    animation: animate 5s linear infinite;
}


/* 这里的椭圆数值 用到的网址：https://mdbootstrap.com/docs/standard/tools/design/fancy-border-radius/*/

.loader span:nth-child(1) {
    border-radius: 44% 56% 58% 42% / 52% 49% 51% 48%;
}

.loader span:nth-child(2) {
    animation-direction: reverse;
    border-radius: 73% 27% 20% 80% / 40% 33% 67% 60%;
}

.loader span:nth-child(3) {
    animation-duration: 3s;
    border-radius: 42% 58% 64% 36% / 66% 33% 67% 34%;
}

@keyframes animate {
    0% {
        transform: rotate(0deg);
    }
    100% {
        transform: rotate(360deg);
    }
}

.loader h2 {
    color: skyblue;
    font-family: consolas;
    font-weight: 500;
    box-shadow: 2px 0 0 #fff;
    /* 将超出的部分进行隐藏 */
    overflow: hidden;
    /* 语法：animation: name duration timing-function delay iteration-count direction fill-mode play-state; */
    animation: textTyping 3s linear infinite;
}


/*定义动画，keyframe是关键帧，里面的百分比要是整数  */

@keyframes textTyping {
    0% {
        width: 0px;
    }
    20% {
        width: 131.96px;
    }
}
