Course Introduction：The tab-size attribute is used to control the number of spaces displayed by tab characters in HTML. The default is 8. The common usage is to adjust the indentation of the code block. 1. Basic usage: Set pre{tab-size:4;} to make the tab appear as 4 space widths, supporting numbers or inherit values. 2. Usage scenario: When displaying code in the structure, adjust the tab indent to make the layout more compact and beautiful, such as setting precode{tab-size:2;}. 3. Notes: Mainstream browsers support but IE is incompatible; it only affects tab display and does not affect spaces; child elements need to be set separately, otherwise the parent settings will not be inherited. The rational use of this attribute can improve the text display effect, especially for code document typesetting.

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.
