著意登樓瞻玉兔，何人張幕遮銀闕？又到了一年一度的網頁小掛件環節，以往我們都是集成別人開源的組件，但所謂熟讀唐詩三百首，不會做詩也會吟，熟讀了別人的東西，做幾首打油詩也是可以的，但若不能自出機抒，卻也成不了大事，所以本次我們從零開始制作屬于自己的網頁小掛件，博君一曬，
玉兔主題元素繪制
成本最低的繪制方式是使用純CSS，不依賴任何圖片和三方庫，首先創建繪制容器：
<div id="rabbit_box">
</div>
由于是小掛件，我們首先將容器固定在右下角：
#rabbit_box{
position: fixed;
bottom: var(--pos,5%);
right: 35px;
z-index: 99;
border: none;
outline: none;
filter: drop-shadow(3px 5px 2px rgb(0 0 0 / 0.4));
}
這里加了一層filter濾鏡，可以讓玉兔更加立體，
考慮到復用性和可移植性，將主題元素動態添加到容器中：
function rabbit_init(){
var container = document.getElementById("rabbit_box");
container.innerHTML = '<div ><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div></div>';
}
rabbit_init()
這里玉兔元素由八個小組件構成，分別是頭部，四肢，四爪，兩只耳朵，眼睛，尾巴以及嘴，
隨后設定CSS樣式：
.rabbit .rabbit__body {
width: 4em;
height: 5.6em;
background: #F4F4F4;
border-radius: 50% 50% 50% 50%/60% 60% 40% 40%;
transform: rotate(-40deg);
box-shadow: inset -2.3em -2.7em 0 0 var(--theme-color,#D2DAEE);
}
兔子身體元素通過border-radius來獲得圓潤的曲線，同時使用transform旋轉元素得到一個適合的角度，最后通過box-shadow屬性來設定顏色，顏色可以自定義，如果沒有自定義則使用默認值#D2DAEE，注意旋轉角度需要指定單位：deg，
接著繪制頭部：
.rabbit .rabbit__head {
position: absolute;
width: 4em;
height: 4.6em;
top: -2.5em;
left: -2em;
background: var(--theme-color,#e1e6f4);
border-radius: 50% 50% 50% 50%/65% 60% 40% 35%;
transform: rotate(-120deg);
overflow: hidden;
}
.rabbit .rabbit__head:before {
content: "";
position: absolute;
width: 0.65em;
height: 0.5em;
top: -0.1em;
left: 1.8em;
background: #F97996;
border-radius: 50% 50% 50% 50%/30% 30% 70% 70%;
transform: rotate(130deg);
}
.rabbit .rabbit__head:after {
content: "";
position: absolute;
width: 1em;
height: 1em;
top: 1.5em;
left: 1.6em;
background: #F4F4F4;
border-radius: 50%;
box-shadow: inset 0.1em 0.15em 0 0.37em #e2262e;
}
這里通過::before 和 ::after 偽元素在兔子頭部元素的前面或后面插入內容，頭部前面繪制兔嘴，后面則插入兔子眼睛，之所以這樣控制，是因為可以靈活的使用box-shadow填充顏色，
接著繪制耳朵：
.rabbit .rabbit__ear {
position: absolute;
border-radius: 50% 50% 50% 50%/40% 40% 60% 60%;
transform-origin: 50% 100%;
}
.rabbit .rabbit__ear--left {
width: 2.2em;
height: 4.7em;
top: -5.7em;
left: -0.2em;
background: #F3E3DE;
transform: rotate(60deg);
box-shadow: inset 0.3em -0.4em 0 -0.1em var(--theme-color,#c7d1ea);
-webkit-animation: ear-left 3s infinite ease-out;
animation: ear-left 3s infinite ease-out;
}
.rabbit .rabbit__ear--right {
width: 2em;
height: 4.7em;
top: -5.5em;
left: -0.7em;
background: var(--theme-color,#D2DAEE);
transform: rotate(20deg);
-webkit-animation: ear-right 3s infinite ease-out;
animation: ear-right 3s infinite ease-out;
}
@-webkit-keyframes ear-left {
0%, 20%, 100% {
transform: rotate(40deg);
}
10%, 30%, 80% {
transform: rotate(45deg);
}
90% {
transform: rotate(50deg);
}
}
@keyframes ear-left {
0%, 20%, 100% {
transform: rotate(40deg);
}
10%, 30%, 80% {
transform: rotate(45deg);
}
90% {
transform: rotate(50deg);
}
}
@-webkit-keyframes ear-right {
0%, 20%, 100% {
transform: rotate(10deg);
}
10%, 30%, 80% {
transform: rotate(5deg);
}
90% {
transform: rotate(0deg);
}
}
@keyframes ear-right {
0%, 20%, 100% {
transform: rotate(10deg);
}
10%, 30%, 80% {
transform: rotate(5deg);
}
90% {
transform: rotate(0deg);
}
}
這里通過-webkit-animation屬性讓兔子左右耳在3秒內進行來回擺動，達到一種動態效果，注意左耳內側顏色固定為：#F3E3DE，同時影片會影響元素的布局，需要注意元素的寬高，
最后就是四肢和尾巴：
.rabbit .rabbit__leg {
position: absolute;
}
.rabbit .rabbit__leg--one {
width: 0.8em;
height: 3em;
top: 2.3em;
left: 0.2em;
background: var(--theme-color,#c7d1ea);
border-radius: 50% 50% 50% 50%/30% 30% 70% 70%;
transform-origin: 50% 0%;
transform: rotate(15deg);
}
.rabbit .rabbit__leg--one:before {
content: "";
position: absolute;
width: 0.8em;
height: 0.5em;
top: 2.6em;
left: -0.2em;
background: #f3f6ff;
border-radius: 50% 50% 50% 50%/70% 70% 30% 30%;
transform: rotate(-10deg);
}
.rabbit .rabbit__leg--three {
width: 0.9em;
height: 3em;
top: 2.4em;
left: 0.7em;
background: var(--theme-color,#e1e6f4);
border-radius: 50% 50% 50% 50%/30% 30% 70% 70%;
transform-origin: 50% 0%;
transform: rotate(10deg);
}
.rabbit .rabbit__leg--three:before {
content: "";
position: absolute;
width: 0.8em;
height: 0.5em;
top: 2.6em;
left: -0.2em;
background: #f3f6ff;
border-radius: 50% 50% 50% 50%/70% 70% 30% 30%;
transform: rotate(-10deg);
}
.rabbit .rabbit__leg--two {
width: 2.6em;
height: 3.6em;
top: 1.7em;
left: 1.6em;
background: #c7d1ea;
border-radius: 50% 50% 50% 50%/50% 50% 50% 50%;
transform-origin: 50% 0%;
transform: rotate(10deg);
}
.rabbit .rabbit__leg--two:before {
content: "";
position: absolute;
width: 1.6em;
height: 0.8em;
top: 3.05em;
left: 0em;
background: #f3f6ff;
border-radius: 50% 50% 50% 50%/70% 70% 30% 30%;
transform: rotate(-10deg);
}
.rabbit .rabbit__leg--four {
width: 2.6em;
height: 3.6em;
top: 1.8em;
left: 2.1em;
background: var(--theme-color,#e1e6f4);
border-radius: 50% 50% 50% 50%/50% 50% 50% 50%;
transform-origin: 50% 0%;
transform: rotate(10deg);
}
.rabbit .rabbit__leg--four:before {
content: "";
position: absolute;
width: 1.6em;
height: 0.8em;
top: 3.05em;
left: 0em;
background: #f3f6ff;
border-radius: 50% 50% 50% 50%/70% 70% 30% 30%;
transform: rotate(-10deg);
}
.rabbit .rabbit__tail {
position: absolute;
width: 0.9em;
height: 0.9em;
top: 3.7em;
left: 4em;
background: var(--theme-color,#D2DAEE);
transform: rotate(25deg);
}
.rabbit .rabbit__tail:after, .rabbit .rabbit__tail:before {
content: "";
position: absolute;
width: 100%;
height: 100%;
background: var(--theme-color,#D2DAEE);
border-radius: 50%;
}
.rabbit .rabbit__tail:before {
top: 0;
left: -50%;
}
.rabbit .rabbit__tail:after {
top: 50%;
left: 0;
}
這里四肢和四爪的顏色應該有差異，四肢顏色可以自定義，四爪固定為白色，以達到“四蹄踏雪”的效果，
接著改造初始化函式，使其可以動態更改顏色：
function rabbit_init(color=null,pos=null){
var container = document.getElementById("rabbit_box");
container.innerHTML = '<div ><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div><div ></div></div>';
if(color != null){
document.documentElement.style.setProperty("--theme-color",color);
}
if(pos != null){
document.documentElement.style.setProperty("--pos",pos);
}
}
rabbit_init("pink")
最終效果：

保存在專案的lib目錄，
首先將專案提交到Github: https://github.com/zcxey2911/rabbit
隨后運行命令填寫NPM配置：
npm init
entry point 配置項填寫你的入口檔案：
entry point: ./lib/rabbit.js
登錄NPM賬號，隨后發布：
npm login
npm publish
登錄之前，最好將切換回默認源，否則無法登錄：
npm config set registry=https://registry.npmjs.com
發布成功后，查看發布內容：https://www.npmjs.com/package/rabbit-widget
開源庫引入和使用
首先需要引入模塊，可以使用 CDN 直接引入或者通過 NPM 包的形式安裝，
直接引入：
<!-- https://cdn.jsdelivr.net/gh/zcxey2911/[email protected]/lib/rabbit.css -->
<!-- https://cdn.jsdelivr.net/gh/zcxey2911/[email protected]/lib/rabbit.js -->
<link
rel="stylesheet"
href="https://cdn.jsdelivr.net/gh/zcxey2911/[email protected]/lib/rabbit.css"
/>
<div id="rabbit_box">
</div>
<script>
function init_rabbit(){
rabbit_init("pink","20%"); // 粉色 高度20%
//rabbit_init(); //默認顏色 默認位置
}
</script>
<script
async
onl oad="init_rabbit()"
src="https://cdn.jsdelivr.net/gh/zcxey2911/[email protected]/lib/rabbit.js"
></script>
NPM 包的形式安裝：
// npm install --save rabbit-widget
import 'rabbit-widget/lib/rabbit.css';
var rabbit_init = require('rabbit-widget');
rabbit_init();
如果使用NPM匯入模塊的形式引入，請確保頁面加載完畢之后執行再執行rabbit_init();，否則會報錯：Uncaught TypeError: Cannot set properties of null (setting 'innerHTML')，
這里以Vue.js3.0組件為例子：
<template>
<a-layout >
<a-layout-header>
<div />
<ad_header />
</a-layout-header>
<a-layout-content style="padding: 0 50px">
<a-breadcrumb style="margin: 16px 0">
<a-breadcrumb-item>廣告平臺</a-breadcrumb-item>
<a-breadcrumb-item>首頁</a-breadcrumb-item>
</a-breadcrumb>
<div :style="{ background: '#fff', padding: '24px', minHeight: '280px' }">
這里是首頁
<div id="rabbit_box"></div>
</div>
</a-layout-content>
<a-layout-footer style="text-align: center">
在線廣告平臺
</a-layout-footer>
</a-layout>
</template>
<script>
import ad_header from './ad_header';
import 'rabbit-widget/lib/rabbit.css';
var rabbit_init = require('rabbit-widget');
export default {
data() {
return {
}
},
//宣告子組件
components:{
'ad_header':ad_header
},
methods:{
},
created(){
this.$nextTick(() => {
console.log("頁面加載完啦~")
rabbit_init();
})
}
}
</script>
<style>
.site-layout-content {
min-height: 280px;
padding: 24px;
background: #fff;
}
#components-layout-demo-top .logo {
float: left;
width: 120px;
height: 31px;
margin: 16px 24px 16px 0;
background: rgba(255, 255, 255, 0.3);
}
.ant-row-rtl #components-layout-demo-top .logo {
float: right;
margin: 16px 0 16px 24px;
}
[data-theme='dark'] .site-layout-content {
background: #141414;
}
</style>
