1. Stylish needs to be charged, only 3 custom styles are allowed to be added. When adding the 4th style to save, it automatically jumps to its official website, adding failed. as shown in Figure 1

2. Although the price is not too expensive, like some more rigid software and services, if you need to buy dozens of them in a year, it is still a big expense. And I just need to change the background color of the web page, no other powerful functions are needed. Reference:https://www.shuijingwanwq.com/2017/09/06/1880/

4. After installation, the final use interface is as follows, the user interface is more friendly than Stylish. The usage method is similar to that of Stylish. as shown in Figure 3
