问题描述

如何使用css给任何元素边框而不添加border-width到元素的整个宽度？

How to give border to any element using css without adding border-width to the whole width of element?

像Photoshop一样，我们可以给stroke-和外面

Like in Photoshop we can give stroke- Inside , center and outside

我认为默认的css边框属性是中心像photoshop中心，是吗？

I think default css border properties is center like center in photoshop, am i right?

想给边框里面的盒子不在外面。并且不希望在框宽中包含边框宽度。

I want to give border inside the box not outside. and don't want to include border width in box width.

推荐答案

outline:1px solid white;

这不会增加额外的宽度和高度。

This won't add the extra width and height.
