Hi Karl, I think I've done the step correctly as per instructed.
1) creating the folder name include under files directory
2) put a file name head.html in it
3) head.html put the this <link href="files/css/custom.css" rel="stylesheet">
yet the css still dont load on login page. maybe now wait till u trying the windows with laragon as per you stated in the other post. hoping for the best..
This is the path relative to your servers DOCUMENT ROOT. That is why I can't tell you what it is ... What link are you using to load your website into the browser?
im using ip address of the server to load the website into the browser e.g : //10.43.2.250/repository/home.php <-- this is the login page
