Course Introduction：Bootstrap picture centering tips: Basics: Flexbox and Grid systems are used for layout, and text-center only centers the text baseline horizontally. Horizontal centering: Use justify-content-center attribute (Flexbox), or abuse margin: 0 auto; (unstable). Vertical centering: same as above, add align-items: center; the parent container needs to be set to fixed height. Responsive design: Use responsive classes to control layouts under different screen sizes. Common errors: Forgot to set height, abuse margin, ignore responsive design. Performance optimization: Select the appropriate image format, compress the image volume, and avoid excessively large images. **

Course Introduction：The responsiveness of the centered Bootstrap image depends on the specific situation. text-center is only valid for in-line elements, while mx-auto needs to rely on the width of the parent element, which may cause the image to be centered and distorted. The best way to achieve responsive image centering is to use container elements to set width and mx-auto for horizontal centering, or use the Bootstrap grid system to finely control the layout. A common mistake is to use text-center or mx-auto directly on the image. For performance optimization, appropriate image sizes should be used and best practices should be followed. Understanding principles rather than blindly using classes will help avoid traps and write efficient code.

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.
