The Open source project Progresswheel provides us with a wide variety of circular scrollbars, which this article leads readers to use to implement custom scroll bars. In the official demo, a screen shows several styles, and this article only describes one style, that is, centered display, transparent layout. And with static encapsulation, both start and close require a single line of code to complete.
