用CSS border画一个铅笔

2021-10-30 22:34:53 作者：互联网

先上效果图

该例子来自 CSS世界的书中项目

总结技巧如下：

巧用 border 和伪元素来绘制层叠效果。
使用 transform-origin 来改变元素的轴心
使用 filter:drop-shadow 绘制物体阴影

代码如下：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

        .pencil {

            width: 50em;
            height: 3.5em;
            font-size: 12px;

            margin: 0 auto;
            padding-top: 100px;

            filter: drop-shadow(0.4em 0.8em 0.3em grey);
        }
        .taper {
            width: 4em;
            /* background-color: burlywood; */
        }

        .taper::before {
            content: '';
            position: absolute;
