How well do you need to know html&css and JavaScript in order to fully master ASP.NET CORE at a junior level?

Question

ASP.NET

Very young in learning the .NET platform and programming in general. Six months ago, I started learning C # during this time I mastered SQL, now I am finishing my study of ENTITY FRAMEWORK CORE according to the manual on metanit. I plan to develop into web development in connection with which the above question arose. Maybe tell me about what topics to study JS or what needs to be covered and what not, so that there are no difficulties in mastering asp.net core.

Answer 1

Applications are now created on 2 approaches:
1. api
2. php style (razor, etc.)
In the case of the first one, you don't know and don't do anything at all on the front. You have a contract and you fulfill it, let's say
GET /api/news
is a news feed.
In the second case, you still need to know, but again, if you work in a team, the layout designer will give you the code that you need to spit out. Here you need to know the main tags, maybe a little css to correct the output. In general, nothing extraordinary. Just be able to communicate and ask.
In ASP .NET, things are a little more complicated, but this does not concern you.
