It is implemented through two core properties of scroll-snap-type and scroll-snap-align.

Common application scenarios include horizontal scrolling cards, full-screen vertical scrolling pages, step-by-step guidance and mobile application-style sliding navigation. When using it, make sure that the parent container is scrollable, and it is recommended to match flex or grid layout; at the same time, pay attention to the difference between mandatory and proximity, and combine scroll-behavior

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
