CSS负z-index:是什么意思? [英] CSS negative z-index: what does it mean?

问题描述

如果我向元素的z-index属性添加负整数值，那么根据标准，预期效果是什么?

What is the expected effect according to the standards, if I add a negative integer value to the z-index property of an element?

我搜索了答案，但只找到了这个答案:
https://developer.mozilla.org/zh-CN/docs/Web/CSS/z-index
负值会降低优先级" 对我来说没有任何意义.

I searched for the answer but only have found this:
https://developer.mozilla.org/en-US/docs/Web/CSS/z-index
The "Negative values to lower the priority" doesn't mean anything for me.

推荐答案

z索引为负的元素将在大多数元素下呈现，除非它们的z索引更低.

An element with a negative z-index will be rendered under most elements, unless they have an even lower z-index.
