html - CSS3能写出这种环状吗，不是环形进度条？

问题描述

问 题

抛开颜色不看 ，只是这种排版做得到吗？

解决方案

效果图：

用了SCSS来写，如果不太熟悉的话，可以看CSS。话不多说，直接上代码

index.html

<div class="loading">
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
    <div></div>
</div>

loading.scss

// 线条总数
$total: 13;
// 每个线条相差的角度
$angel: 180/($total - 1);

.loading {
    background: black;
    width: 400px;
    height: 400px;
    position: relative;
    div {
        position: absolute;
        display: block;
        width: 100%;
        height: 2px;
        top: 50%;
        transform-origin: 50% 50%;
        &:before {
            display: block;
            content: "";
            height: 100%;
            width: 10%;
            background: white;
        }
        @for $i from 1 through $total {
            &:nth-child(#{$i}) {
                transform: translate3d(0, -50%, 0) rotate(#{$angel*($i - 1)}deg);
                opacity: 0.2 + 0.8 * $i / $total;
            }
        }
