Course Introduction：Key Points The position: sticky property of CSS allows the navigation bar or other elements to remain visible when the user scrolls without having to pin it on the page. This property acts like a static position within its parent element until the given offset threshold is reached, at which point it is like the value is set to fixed.

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.
