Course Introduction：Bootstrap provides three image centering strategies: using mx-auto (recommended), flexbox, or grid systems. mx-auto Set the left and right margins to auto to achieve automatic horizontal centering. The flexbox layout provides more flexible control. The grid system allows centering pictures in the grid structure. Avoid common mistakes such as forgetting img-fluid, not defining the parent element width or using the centering method. Optimize images and follow Bootstrap best practices to improve code quality and performance.

Course Introduction：Centering a Bootstrap picture not only involves horizontal centering (mx-auto), but also requires vertical centering. Common vertical centering schemes are: Flexbox: add d-flex and align-items-center classes. Grid layout: Use col-auto and row justify-content-center. Absolute positioning transform: absolutely position the image and use transform: translateY(-50%). Selecting the right solution and combining Bootstrap's grid system and Flexbox/Grid layout can achieve efficient and elegant picture centering layout.

Course Introduction：Why can't margin: auto center Bootstrap image? Because the parent element of Bootstrap usually has no clear width, margin: auto fails. Reliable picture centering scheme: Use the text-center class (simple, but only for single-line images) Use Flexbox layout (powerful, suitable for single-line and multi-line images) Use Grid layout (fine-grained control for complex layouts) Best practice: Choose methods based on needs, consider performance and best practices, and write clear and easy-to-maintain code.

Course Introduction：The use of padding in the center of the Bootstrap image is unreliable, and it is affected by the size and content of the parent element, which can cause problems. A more secure and efficient solution is to use margin: 0 auto; (horizontal centered) or Flexbox/Grid layouts (horizontal and vertical centered), which are more powerful and flexible. Avoid over-dependence on padding to implement layout, select appropriate layout solutions, maintain code consistency, and use developer tools to debug layout problems.

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.
