dot slash vs nothing. What is the difference and what's better to use?

Question

Just for curiosity.

What is the better method to use and what is the difference between them ?

<link rel=stylesheet href="./css/css.css">

vs

<link rel=stylesheet href="css/css.css">

Answer 1

In a relative URI, there is no difference between them.

Going without the ./ will save you 2 bytes, so it is marginally better.

---

In a UNIX style shell, leaving the ./ off will search $PATH while including it will search the current directory. Some people might be including the ./ out of habit from working on the shell.

Answer 2

ultimately, there is no difference. They both produce the same link to the same file.

As Quentin just said, it saves you 2 bytes in storage, but I suppose even that doesn't really make a difference.

It just somes down to personal preference/coding style. I never use the ./, never found the use for it. However, people from linux might prefer it, since there it is used to indicate the current directory a lot.
