css优雅的画出形状图形
CSS 可以制作出各种我们日常需要的形状。比如说正方形和矩形制作就很简单,添加一个宽度和高度,就得到了所需的矩形大小。如果我们再给它添加一个 border-radius 属性,你就可以把这些矩形变成圆形和椭圆形。当然我们还可以用 CSS 中的伪元素::before 和::after,使我们可以在原始元素中添加另外两个形状。通过巧妙地定位、转换和其他技巧,我们可以只用一个 HTML 元素在 CSS 中创建许多形状。有了这中 css 的形状写法好处当然是很多,我们不用在找美工妹子为我们设计那么多图片,只要我们喜欢愿意就可以几行代码搞定需要的形状,这样我们的网页打开速度也快了。好了,废话不多说,步入正题吧。
