css圆角三角形3个圆角

CSS | 圆角 (CSS | Rounded Corners)

border-radius property is commonly used to convert box elements into circles. We can convert box elements into the circle element by setting the border-radius to half of the length of a square element.

border-radius属性通常用于将框元素转换为圆形。 通过将边框半径设置为正方形元素长度的一半,我们可以将框元素转换为圆形元素。

Basic syntax:

基本语法:

Element {
width: 150px;
height: 150px;
border-radius: 50%;
