Question

css

Hi all! I have a graduation project on the topic "Development of a student portal" and I need to create a site with a minimum investment of knowledge :) But the site should directly contain "Student Registration / Authorization", etc. things.
I know that you can make a website even with C++, Python, everything depends on you, etc.
But I need to make it easier to do and actually protect.
