45个值得收藏的 CSS 形状

CSS能够生成各种形状。正方形和矩形很容易,因为它们是 web 的自然形状。添加宽度和高度,就得到了所需的精确大小的矩形。添加边框半径,你就可以把这个形状变成圆形,足够多的边框半径,你就可以把这些矩形变成圆形和椭圆形。

我们还可以使用 CSS 伪元素中的 ::before 和 ::after,这为我们提供了向原始元素添加另外两个形状的可能性。通过巧妙地使用定位、转换和许多其他技巧,我们可以只用一个 HTML 元素在 CSS 中创建许多形状。

虽然我们现在大都使用字体图标或者svg图片,似乎使用 CSS 来做图标意义不是很大,但怎么实现这些图标用到的一些技巧及思路是很值得我们的学习。
