margin-top和-webkit-margin-before有什么区别 [英] What is the difference of margin-top and -webkit-margin-before

问题描述

Webkit添加了其自己的特定边距，即:

Webkit have added its own specific margins which are:

-webkit-margin-before:
-webkit-margin-after:
-webkit-margin-start:
-webkit-margin-end:

我了解(margin-left和-webkit-margin-start)或(margin-right和-webkit-margin-end)与从左到右"或从右到左"语言相关的区别.

I understand the difference of (margin-left and -webkit-margin-start) or (margin-right and -webkit-margin-end) which is related to "left to right" or "right to left" languages.

我的问题是(margin-top和-webkit-margin-before)或(margin-bottom和-webkit-margin-after)之间有什么区别?

My question is what is the difference between (margin-top and -webkit-margin-before) or (margin-bottom and -webkit-margin-after) ?

注意:很明显，-webkit前缀仅适用于chrome和safari等webkit引擎浏览器.这个问题与此无关.

Note: It is obvious that -webkit prefix only works on webkit engine browsers such as chrome and safari. This question is not related to it.

推荐答案

到目前为止，我能找到的最佳答案是-web-margin-before在普通文档中的作用与margin-top相同，但在底部至顶部"(相同的想法适用于-webkit-margin-after).

The best answer I could find so far is -web-margin-before acts same as margin-top on normal documents but it will act as margin-bottom on "bottom to top" languages (same idea applies to -webkit-margin-after).
