HTML file is not running anything
I created PHP Empty Project. PHP file is running. but I need to use html file to get data.
The main issue here is that html file is not even getting external css file. Neither javascript nor PHP within it is working.
I need to add these files externally but I have tried internally and still no response.


Another thing I noticed that it want Node.js for simple javascript file.
I am new to Web Development too. Currently a Student.

Yes, it's expected - PhpStorm can't itself execute JavaScript, Node.js interpreter is required for running server-side code.
