获取:before伪元素使用父级的背景图像 [英] Getting :before pseudo element to use background image of parent
问题描述
可以使用CSS来设置a:before伪元素的背景图像与其父元素相同。我想说继承,但是一个伪元素可以继承什么吗?示例:
Can CSS be used to set the background image of a :before pseudo element to the same as it's parent. I want to say inherit, but can a pseudo element inherit anything? Example:
li a {
background: #f56a46 url(images/gallery-thumb.jpg) center center no-repeat;
}
li a:before {
background: inherit;
}
我知道我可以很容易地使用JavaScript,但我想知道可能只使用CSS。任何帮助将非常感谢,谢谢!
I know I could easily do it with JavaScript but I want to know if it's possible using only CSS. Any help would be much appreciated, Thanks!

和尺寸,所以伪元素有一个框,必须显示背景?
