I have created one repository on GitHub and host with the help of the GitHub page. My issue is that if I have put all code (CSS, JavaScript code) in HTML then it works, but if I have created another folder of CSS and JavaScript, and saved the path in HTML, then it's not working. I don't understand why.
For example, you create one simple hello world website and try code from this condition.
Repository link: Aj Zero Coding
Website link: Aj Zero Coding
Output link: Project (I want to this output).
