Course Introduction：The key to making a responsive navigation bar is to realize the collapse function of the menu on the small screen. The core steps include: 1. Building an HTML structure, including containers, logos, links and hidden hamburger buttons; 2. Using CSS media to query and control styles under different screen sizes, hiding the menu on the mobile terminal and displaying the hamburger buttons; 3. Using JS to realize the interactive logic of click expansion and collapse. Specifically: the navigation items are displayed in HTML.nav-links, and the .hamburger button is hidden by default; the menu is set in CSS to absolutely position and hide the menu, and the hamburger button is displayed; JS controls the menu expansion and collapse by switching the .active class to ensure smooth interaction.

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.
