代码解读

定义 dom，容器表示邮票：

<div class="stamp"></div>

居中显示：

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

设置容器尺寸：

.stamp {    position: relative;    width: 57em;    height: 71em;    font-size: 5px;    padding: 5em;    background-color: white;}

用重复背景绘制出邮票的齿孔：

.stamp {    display: flex;    flex-direction: column;    align-items: center;    justify-content: center;}.stamp::after,.stamp::before {    content: '';    width: 100%;    height: 100%;    position: absolute;    background:         radial-gradient(circle, teal 50%, transparent 50%),        radial-gradient(circle, teal 50%, transparent 50%);    background-size: 3.5em 3.5em;}.stamp::before {    top: 1.5em;    background-repeat: repeat-y;    background-position: -3% 0, 103% 0;}.stamp::after {    left: 1.5em;    background-repeat: repeat-x;    background-position: 0 -2.5%, 0 102.5%;}

在 html 文件中增加小鸡的 dom 元素，子元素分别表示头部、喙、身体、尾巴、腿、爪子、太阳、桔子：

<div class="stamp">    <div class="rooster">        <span class="head"></span>        <span class="beak"></span>        <span class="body"></span>        <span class="tail"></span>        <span class="leg"></span>        <span class="foot"></span>        <span class="sun"></span>        <span class="orange-stuff"></span>    </div></div>

设置 grid 布局的行列尺寸：

.rooster {    display: grid;    grid-template-columns: 22.5em 13em 1.75em 14.5em 4.5em;    grid-template-rows: 12.5em 14.5em 15em 8em 5.5em;    background-color: wheat;    padding: 2em;    margin-top: -2em;}

画出扇形的头部：

.head {    grid-column: 4;    grid-row: 2;    background-color: burlywood;    border-top-left-radius: 100%;}

画出小鸡的眼睛和脸上的红晕：

.head {    position: relative;}.head::after {    content: '';    position: absolute;    width: 2.8em;    height: 2.8em;    border-radius: 50%;    background-color: black;    right: 30%;    box-shadow: 2em 4em 4em rgba(255, 100, 0, 0.5);}

画出扇形的喙：

.beak {    grid-column: 5;    grid-row: 2;    height: 4.5em;    background-color: darkorange;    border-bottom-right-radius: 100%;}

画出半圆形的身体：

.body {    grid-column: 2 / 5;    grid-row: 3;    width: 30em;    background-color: saddlebrown;    border-radius: 0 0 15em 15em;}

用伪元素，通过阴影画出翅膀：

.body {    position: relative;    overflow: hidden;}.body::after {    content: '';    position: absolute;    width: 20em;    height: 10em;    border-radius: inherit;    box-shadow: 4em 2em 4em rgba(0, 0, 0, 0.3);    left: calc((30em - 20em) / 2);}

画出扇形的尾巴：

.tail {    grid-column: 1;    grid-row: 1 / 3;    height: 22.5em;    background-color: burlywood;    align-self: end;    border-top-left-radius: 100%;}

画出扇形的腿：

.leg {    grid-column: 4;    grid-row: 4;    width: 8em;    background-color: burlywood;    border-bottom-right-radius: 100%;}

画出扇形的小爪子：

.foot {    grid-column: 4;    grid-row: 5;    width: 5.5em;    background-color: darkorange;    border-top-right-radius: 100%;}

画出半圆形的太阳：

.sun {    grid-column: 3 / 5;    grid-row: 1;    width: 17em;    --h: calc(17em / 2);    height: var(--h);    background-color: darkorange;    border-radius: 0 0 var(--h) var(--h);}

画出圆形的桔子和半圆形的叶片，注意此处叶片的画法与前面画半圆形的画法不同：

.orange-stuff {    grid-column: 1;    grid-row: 3 / 6;    width: 16em;    height: 16em;    background-color: darkorange;    align-self: end;    justify-self: end;    border-radius: 50%;    position: relative;}.orange-stuff::before {    content: '';    position: absolute;    width: 8em;    height: 8em;    background: linear-gradient(45deg, transparent 50%, saddlebrown 50%);    border-radius: 50%;    top: -6.8em;    left: 10%;}

在 dom 中再增加一些文本，包括标题、作者和面值：

<div class="stamp">    <div class="puppy">        <!-- 略 -->    </div>    <p class="text">        <span class="title">Rooster</span>        <span class="author">comehope</span>        <span class="face-value">120</span>    </p></div>

设置标题的文字样式：

.text {    position: relative;    width: calc(100% + 2em * 2);    height: 6em;    font-family: sans-serif;}.text .title {    position: absolute;    font-size: 6em;    font-weight: bold;    color: brown;}

设置作者的文字样式：

.text .author {    position: absolute;    font-size: 3em;    bottom: -1.2em;    color: dimgray;}

设置面值的文字样式：

.text .face-value {    position: absolute;    font-size: 14em;    right: 0;    line-height: 0.9em;    color: darkcyan;}

大功告成!
