I have created a project which is working fine when I open it with VSCode live server (127.0.0.1:5501/index.html).

The following is the image of the scripts in the index.html, and the files path.

The css file for leaflet.css located in the head of index.html looks like this:
<link rel="stylesheet" href="vendors/leaflet/leaflet.css">
I'm currently using XAMPP to run my app and the project is located in the htdocs.
Whenever I run the code with XAMPP, I get the following:

So, the map is not showing. The errors show up:
GET http://localhost/project1/vendors/leaflet/leaflet.css net::ERR_ABORTED 403 (Forbidden)
GET http://localhost/project1/vendors/leaflet/leaflet.js net::ERR_ABORTED 403 (Forbidden)
I would appreciate any help.
