Course Introduction：Bootstrap picture centering tips: Use the grid system to center horizontally: justify-content-center class to center horizontally, col-auto allows the picture to adapt as needed, and img-fluid adapts to container size. Use Flexbox to center vertically: d-flex sets the container to the Flex container, align-items: center vertically. Try to use Bootstrap's own classes, follow concise code guidelines, avoid custom styles, excessive nesting, and improve the readability and efficiency of the code.

Course Introduction：This tutorial aims to solve the problem that when the WooCommerce classification page uses ACF custom fields to display multiple images, some fields are empty, which causes empty spaces to be displayed. By adopting an array to collect effective image links and render dynamically, we can effectively avoid redundant conditional judgments and ensure that only actual existing images are displayed, thereby improving the simplicity, maintainability and user experience of the 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.
