Can do front-end and background. If you can't basically do anything, you can look at how other systems or websites with the same topic were implemented in the early stage and see how they did it. Then extract the functions you want, record them, and then summarize them. At this time, the database fields in your general database will come out, then design the database structure and write the code. First, choose a set of templates that you like or think you can.

Then add, delete, change and check in the background first, and then do the front end. After the current backend is finished, the general system will come out. Simple students can make a set of library management system or student management system first. These functions and database fields are easy to understand. Just be the front desk and backstage.

What a website must do is front-end and background, that is, html pages and background servers.

Users can send commands to the server by clicking the corresponding buttons on the front page. After the server receives the command, it calls the corresponding code and responds to the database. Complete the entire operation command.

The knowledge used in the front end must be html+js+css.

The server can choose to use java or php or python.

Personally, I suggest learning php. I learned java first, then php. When I was studying php, I only studied for three hours and made a website by myself. The function is quite complicated.

So the general technical route is html+css+js+php.
