Background programmers want to make a page that conforms to the aesthetic of the times (light, simple / fashionable). Which technologies can be preferred?

I want to do a micro-level chat system by myself. I usually work as a background developer. I want to sum up and practice what the project team has learned through this small project, and at the same time actively understand and learn some popular new technologies.
the purpose of asking you a question is to know which technologies you can choose to make a page that is in line with the aesthetics of the times (light, simple / fashionable).
the front-end technology involved in the work is that jquery and javascript, have previously come into contact with bootstrap, to understand the 3D characteristics of html5, and have drawn a 3D diagram of the solar system (forming a sphere by rotating a circle). Recently I have been reading the official documents of vuejs.
also a very important point is that because I work as a background developer, I don"t want to spend too much energy on front-end learning, but because I have certain aesthetic requirements, even if it"s just practice, I hope my work won"t be miserable.
I hope you can give me some suggestions. Thank you very much!

basic aesthetic appreciation should be possible

written by vue.js Chinese, the document contains Chinese is very convenient, and very complete, real-time chat system is generally implemented by websocket, aesthetic words do not want to refer to other chat system design, look at their ui to conditional choice, the general user is sure to be accepted by the public, so do not according to their own ideas, to learn from
