“./"是什么意思?(点斜线)是指 HTML 文件路径位置?
我知道 ../ 的意思是走一条路径，但是 ./ 到底是什么意思?
I know ../ means go up a path, but what does ./ mean exactly?
我最近正在阅读一个教程，它似乎只是指同一位置的一个文件，所以有必要吗?如果仅此而已，我可以不使用它吗?
I was recently going through a tutorial and it seems to be referring to just a file in the same location, so is it necessary at all? Can I just not use it if that's all it's doing?
./ 是 working 文件所在的文件夹:
./ is the the folder that the working file is in:
所以在/index.htm中./就是根目录
但在 /css/style.css 中 ./ 是 css 文件夹.
So in /index.htm ./ is the root directory
but in /css/style.css ./ is the css folder.
记住这一点很重要，因为如果你将 CSS 从 /index.htm 移动到 /css/style.css 路径将会改变.
This is important to remember because if you move CSS from /index.htm to /css/style.css the path will change.
