HTML，CSS 和 JavaScript 是 Web 页面的“三驾马车”，分别负责网页的结构、样式和行为，共同组成了丰富多彩的 Web 世界。一个完整的网页，通常少不了其中任何一个。
提到网页绘图，我们往往会想到用 canvas、svg 或者 WebGL，甚至直接用各种图片格式。但是，你想过只用 HTML 和 CSS 能实现多复杂的视觉效果吗？做过几年前端开发就知道，CSS 3 确实很强大，能实现很多意想不到的效果。最近在网上看到一位大神的作品，更是惊掉了下巴：只用一个 div 元素，加上 CSS 代码，就实现了很多惊艳的图形和动画！
让我们一起来膜拜学习吧！

还有更多的图案和动效，这里就不一一贴出来了。光看这几个，就不得不佩服作者的想象力和 CSS 功夫了。这位大神叫 Lynn Fisher，这个项目 Demo 网站是https://a.singlediv.com/，正如域名的含义：只用一个 div。是不是很神奇？
在图形绘制方面跟 SVG 相比，这样的实现方式虽然不太实用，而且还可能有浏览器兼容问题。但是不得不说，这样的思路确实很清奇，同时也体现了 CSS 的特性和潜力。
