When cropping in batches, you can achieve unified settings by copying and pasting properties. Cropping will not change the resolution and scale, but excessive cropping may lead to black edges, so you need to pay attention to symmetrical operations or appropriate scaling. Practical applications include adapting horizontal and vertical screen ratios

Course Introduction：Media queries are CSS3 features that are used to dynamically adjust styles according to device attributes to ensure responsive design. It realizes different screen adaptation through @media rules combined with breakpoints (such as max-width, min-width). Common breakpoints include: 1. Mobile phone vertical screen: max-width: 480px; 2. Mobile phone horizontal screen or small tablet: 481px-768px; 3. Tablet and above: ≥769px. There are two ways to organize structure: centralized management by breakpoint is suitable for small projects, and decentralized management by components is conducive to maintenance of large projects. When using it, you should follow the mobile priority principle, adopt relative units, avoid excessive breakpoints, and consider high resolution and printing style adaptation, and cooperate with real machine testing to optimize the experience.

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.
