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：The key to using one line of code to transition multiple attributes is to correctly use the abbreviation of transition attributes and pay attention to performance and compatibility. The specific methods are: 1. Use the all keyword to set the transition of all attributes uniformly, such as transition: all0.3sease; 2. Clearly list multiple attributes that need to be transitioned and set parameters separately, such as transition: background-color0.3sease, border-radius0.3sease; 3. Common application scenarios include button hovering effect, menu expansion/collapse and responsive layout switching; 4. Pay attention to avoid unnecessary attributes for transition, consider browser compatibility, and identifying them that cannot be passed.

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.
