What technologies need to be mastered in web development? Please give me some advice_html/css_WEB-ITnose

I am a computer enthusiast. Now I want to learn WEB development and engage in WEB development in the future. But I don’t know how to study. Very confused

So here I would like to ask for your guidance on how to study. There is no one learning goal. I don’t know that as a qualified and excellent web developer, it is not difficult to find a job by mastering those technologies. What to learn. Let’s learn what we are learning first, and I beg for your advice.
I would like to give you some guidance on both web front-end development and web back-end development. Sorry for your inconvenience. . . . . . . .

html css js, and then learn a backend programming language (as long as you understand it), the backend programming language can be :PHP (relatively simple).

Come on

Thank you. . .
