Course Introduction：Core points Flexbox is a CSS layout model that allows developers to create complex UIs without relying on redundant CSS and JavaScript tricks. It uses a linear layout model, making it easier to layout content horizontally or vertically without spacing calculations. Flexbox can be used to create websites with giant navigation menus. This layout model allows creating simple navigation bars, single drop-down menu segments, and limiting single drop-down menu segments to three columns. The Flex layout is responsive to elements within the container, reducing the need for media queries. The final mega menu created in this tutorial is not fully responsive. The main menu bar will be displayed on a smaller screen, but the giant menu will not be available, only the top links are available

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.
