PHP file view

• First check your css file. Is it available or not.
• If that file is available then check the file directly wether you have access or not. For example, if the file in css directory. Try access it directly by url. Do you get any error?
• If you doesn't have access to directory probably htaccess configuration or directory issue (set the directory access to public or chmod 777) and try to give htaccess to allow all https://httpd.apache.org/docs/current/howto/htaccess.html

Order allow,
deny Allow from all
