Course Introduction：The CSStransform property is used to rotate, scale, tilt and translate elements without affecting the document flow.

Unlike top and left, translate is rendered through GPU, which is more suitable for animation and has better performance. Use transform-origin to adjust the transform center point, supporting two or three values to define the origin position. The order of multiple transformations will affect the final effect, so please be careful to execute the rightmost function first. Mastering these key points allows for smooth and complex visual effects.

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.
