考虑文章篇幅的原因，大部分的小游戏、动画我都只放了HTML部分的代码，具体的CSS、JS代码我都打包放在了一起，具体参考文章末尾。
1.小鹿亲嘴
这两个年轻的小鹿相爱。你可以帮助他们在一起吗？
使用Matter.js物理特性和自定义psuedo-rigging进行构建。已更新为固定大小，以防止某些屏幕尺寸出现对齐问题。
主要HTML代码：

还有CSS和JS代码，列出来的话文章太长了，本文中所有的完整代码都可通过文章末尾的方式获取（CSDN积分下载或者关注公众号啦啦啦好想biu点什么回复情人节表白免费获取）
2.变成小猫
“想变成小猫
每天挠挠你裤脚
这样你还会把我抱一抱”
当然这里的汉字你可以自由发挥，想不出来好点子也可以参考参考别人写的三行情诗或者网上搜一搜一些用来表白的情话。

7.3D旋转相册
这个相册我之前发过，感觉情人节用来表白还是不错的。当然这里的相册可以换成自己的女朋友（没有的话我也没办法）音乐也可以换成自己喜欢的。
基于HTML的3D立方体相册
HTML代码：
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta name="viewport" content="width=div, initial-scale=1.0">

8.用不同的语言说“爱”
这里我用了61个国家的语言翻译的“爱”组成了一个爱心，特别把我们中国的爱弄得又大又红。
HTML非常简单：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Wanghao | love</title>
<link rel="stylesheet" href="css/style.css">
<link rel="icon" type="image/x-icon" href="https://wanghao221.github.io/favicon.ico">
</head>
<body>
<div class="love"></div>
</body>
<script src="js/script.js"></script>
</html>
JS：
const words = [
'爱', 'Love', 'Amour', 'Liebe', 'Amore',
'Amor', 'Любовь', 'الحب', 'प्यार', 'Cinta',
'Αγάπη', '사랑', 'Liefde', 'Dashuri', 'Каханне',
'Ljubav', 'Láska', 'Armastus', 'Mahal', 'אהבה',

'Mahal', 'ярату', 'محبت', 'sopp', 'uthando',
'ความรัก', 'Aşk', 'Tình yêu', 'ליבע'];
const dom = {
love: document.querySelector('.love')
}
dom.love.style.setProperty('--particles', words.length)
words.forEach((word, i) => {
let span = document.createElement('span')
span.style.setProperty('--n', i 1)
span.innerText = word
dom.love.appendChild(span)
})
