Enhance the semantics of the page structure to help users establish logical awareness of the page layout; 4.

Course Introduction：Use tags more standardized but not required. HTML5 semantic tags can improve the clarity of the page structure, and are designed to wrap main navigation links, such as main navigation bar, side menu, footer link group, etc. 1. The main navigation area such as the main navigation bar on the top or sidebar should be used. 2. Auxiliary navigation such as footer links, paging navigation, etc. are also applicable. 3. Multi-link collections are recommended for navigation. Use improves barrier-free experience, facilitates maintenance and facilitates SEO. However, individual jump links, article embedded links, non-navigation-purpose links, etc. can be omitted and used directly. In actual development, it is recommended to use it reasonably to avoid abuse, and to combine ARIA attributes with better style control, and do not affect structural semantics.

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.
