只用 div 和 css 能玩出什么花来?请扶好下巴!

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,可以看出 CSS 的特性和潜力。
