Course Introduction：Understand Bootstrap's grid system and flexibly use column classes to control the layout of list items under different screen sizes. Use col-md-4, col-sm-6 and other classes to set the number of columns of the list item under a specific screen size to achieve responsive effects. For situations where the list items have a lot of content or the layout is complex, use CSS styles or media queries for more fine control to ensure that the page is displayed clearly. Make full use of Bootstrap's responsive tool classes, such as d-none d-md-block, to control the display and hiding of elements under different screen sizes, and improve layout flexibility.

Course Introduction：This article explains the advanced techniques and optimization strategies of WebGL in depth, aiming to improve 3D graphics rendering performance and development efficiency. First of all, it is crucial to understand the mechanism of WebGL as a state machine. Properly managing state switching, avoiding frequent enable/close functions, and using encapsulation functions to control states can reduce errors and improve performance. Secondly, the post-processing effect is achieved through frame buffering (FBO). The steps include creating and binding the frame buffer, attaching colors and depth textures, rendering the scene to texture, and then post-processing on the full-screen quadrilateral, which is suitable for blur, glow, HDR and other effects. Third, using glslify and other tools to organize GLSL code, modular common functions such as Phong lighting model, and unified management of shader compilation process will help

Course Introduction：Selecting the right CSS unit in web design can improve layout flexibility and responsiveness. px is suitable for precise control, such as border or icon size; em is based on the current font size, used for proportional layout but is susceptible to nesting; rem is based on the root element, suitable for global unified design; vw/vh is based on the viewport size, suitable for full-screen layout; % is relative to the parent container, suitable for width or margin settings. In responsive design, rem is used to achieve overall scaling, and combining %, fr or clamp() functions can enhance adaptability and visual effects. Avoid mixing em and rem, use px to set fonts with caution, and recommend unifying rem to improve maintainability. By reasonably matching different units, a more flexible and consistent layout plan can be achieved.

The input box and text field are 100% wide, the inner margin is unified, and blue shadows are displayed when focusing; 5. The submit button is full-width green, hovering to dark green, improving interactive feedback; 6. Reduce spacing and fonts on the small screen through media queries; 7. It is extensible to use flex layout to achieve side-by-side input; 8. It is recommended to add JavaScript verification and error styles to enhance functions. The overall structure is simple and practical, and can be directly integrated into the item

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.
