css 简写属性 数据冲突怎么办?_html/css_WEB-ITnose
比如 利用background简写属性,其中可以写-size -position 那么就出现了两个可以用px表示的值,那么我应该如何处理呢?它是怎么识别我的顺序的。好困惑。。。。
回复讨论(解决方案)
要按规定的顺序写
语法如下
background:[
就是background-position / background-size
background-position要写在 / 的前面
background-size要写在 / 的后面
如果只有background-position 就不写 /
要写background-size 就必须写background-position
太谢谢了~涨姿势啦
