我们将在本文中使用速记属性来设置不同的背景属性。
- 为了减少 CSS 代码的长度,我们可以通过“Shorthand Property”在一行中声明背景属性。
- 通过这个属性,我们可以在一行中定义背景的不同属性,而不是在多行中使用background-color、background-image等属性。
速记属性:
速记属性允许您使用单个属性指定一组相关的 CSS 属性。它们将相关属性组合成一种简写形式。在大多数情况下,如果您省略可选值,浏览器会设置默认值
句法:
background: bg-color bg-image position/bg-size bg-repeat bg-origin bg-clip bg-attachment initial|inherit;
