Focus on learning PHP back-end. If you want to work in the future, to what extent should you master the front-end?

I am currently a sophomore in college, teaching myself PHP. If I want to do PHP back-end development in the future, I would like to ask you guys, what level of mastery of the front-end is appropriate.

div css
jquery operating dom
I think that’s enough

I am both a self-taught PHP student in college and have been working for a year now.

When you first enter the workplace, unless there is a severe shortage of manpower, you will basically be assigned some chores, especially those on the front end

The backend includes but is not limited to modifying specific functions, all operations involved in adding a field to the database, completing a small function point (add, delete, modify, check), etc.

For the front-end, small companies generally use ready-made templates online, such as bootstrap, etc. Larger companies will have professional cutters and front-end designers, so as long as you understand it and can use it, basically You will not be asked to write native html and css

The front-end mainly needs to be learned but is not limited to

<code>后端PHP发过来一段json数据，前端通过ajax接受，并用jquery操作dom的方法填充到html
  jquery操作dom获取html上特定数据通过ajax向后端PHP发json数据并取得返回结果显示在页面上
</code>

If you are familiar with the above set of processes, you can be competent for most jobs. If you are more advanced, some companies will use node.js angularjs mongo and so on.

As long as you can ensure your mastery of PHP, of course the deeper the better.
Don’t think that just learning 8899 is enough~ You will soon be unable to keep up with the times.

Both are sophomores and have taught themselves PHP and have been working for half a year. I think they are very similar to you. Since you only asked about the front-end, let me just tell you what standards the front-end needs to meet

Basics
1. HTML, CSS, these are the most basic things. You can further learn H5 and CSS3, because these two are relatively simple
2 .JavaScript is the most important part and has a higher difficulty index. It is recommended to start with jQuery first. There is no need to learn JavaScript first. After all, jQuery has also withstood the test of time.

Free Stocking Chapter
Based on this, I think you can already make basically readable pages on your own, and you can also use jQuery to write some cool web pages, animations, etc. Ajax, you can use this and that very maturely. Even better, you might have written a few nice little projects and already have users.

In fact, in my opinion, these are enough to help you graduate.

If you want to go in the direction of full-stack Web, you can take a look at the advanced article below.

Advanced Chapter
At this time you already have excellent software design capabilities and have discovered many problems. Writing jQuery is so exciting, but writing too much code (This is a derogatory meaning). What to do? So you keep up with the times and see that there are many front-end libraries or frameworks that can solve things such as modularization and front-end MVC. You check online about requireJS, angular, react, etc., and at this time you may Having graduated and discovered the direction and development trends of these things, you will have your own ideas about which one to study.
