There are several links:
<a href="/path/">Link1</a><a href="/path">Link2</a><a href="./path/">Link3</a><a href="./path">Link4</a>
What is the difference? I tested, but did not understand anything.
PS I know that on the server there is such a thing as a root directory, it is accessed via / as from the main directory and it also applies to the separation of directories. There is also ../ used to go up the hierarchy.
