Many of my friends are afraid of JS, but I have heard from many friends that jQuery is very simple. Therefore, I started to use jQuery and found that I only wrote simple functions, complex functions are not easy to write or are always worried about performance issues. For front-end personnel, they can only solve this problem through continuous learning, but for background programmers or simply users, this will affect the development efficiency! In fact, the jQuery team has solved this problem for everyone, but many of them have not released it. The jQuery team has built a powerful UI framework based on jQuery-jQuery UI. after Long-term improvement and improvement, jQuery UI has many common and practical functions. We only need to make good use of jQuery UI to quickly get the desired results, without writing JS or worrying about performance issues. Many people think of jQuery UI as bloated and ugly. My personal opinion is as follows: Compared with the powerful functions and flexible custom options of jQuery UI, It is not bloated and concise. Although the style is not very beautiful, it can be defined, therefore, this problem can be ignored. If some users often visit websites outside China, they will find that more than 60% of websites reference jquery uI. after all, I want to tell you that jQuery UI is actually excellent and should be good at using it! Today, I have customized a tabs tab style based on jQuery UI! The effect is imitation. In the future, you will get more beautiful styles for your direct use!
