The minimum required to start a web application is to have some basics in HTML and CSS. We are glad to see that you are at ease with it.

As you may already know, web applications can be developed with or without a backend.

Having a backend is quite mandatory if you need:

• Some interactions with a database
• Some interactions with the users
• Some powerful calculations
• Several frontend applications that can use the same backend

This clarified, can you tell me:

Do you need a backend / an API for your application?

• I need backend
• I don't need backend
