The tablet and small-screen devices (768px~1023px) can introduce two-column layouts, uses min-width:768px and max-width:1023px media query, supports horizontal and vertical screen switching; 3. The desktop devices (1024px and above) use min-width:1024px media query, supports multi-column layout and high-definition image sources; 4. Other supplements include separate processing of mobile horizontal screens, large-screen optimization, focusing on viewport size rather than pixel ratio, and flexible use units. Really good

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. **

Use HTML5 semantic tags to build clear structures, such as, , etc., to make the code easier to read and facilitate search engine crawling; 2. Use CSS3 media query to achieve multi-device adaptation, and apply different rules by detecting screen width, such as setting breakpoints such as mobile phones and tablets; 3. Use elastic layout (Flexbox or Grid) to deal with alignment and arrangement issues, and ensure that the navigation bar and other content automatically adapt to the screen; 4. Set image adaptation, use max-width:100% and srcset attributes to ensure that the image does not destroy the layout and improve the loading effect. Mastering these four key points can achieve compatibility with multiple settings

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.
