- Refactoring God Switches: From Complex Conditionals to Clean Code
- Use the policy pattern to replace complex conditional logic based on type or state with extensible policy classes; 2. Eliminate type checking through polymorphism, so that each object can realize its behavior by itself; 3. Replace simple value-to-value or value-to-action mapping with lookup tables (such as dictionaries); 4. Use guard clauses to return in advance to reduce nesting levels; 5. Extract methods to name and isolate conditional logic. These reconstruction methods convert complex conditional statements into clear and maintainable code, improve readability and scalability, and fully follow the principle of opening and closing, ultimately achieving a clean and expressive design.

- How to mark up variables with the var tag in HTML
- Tags are used to semantically identify variables in mathematical, programming, or scientific formulas in web content, rather than variables used in actual programming. 1. Tags should be used in mathematical expressions, programming examples, scientific formulas or placeholders to mark variables; 2. The correct usage is to wrap only the variable itself, such as A or filename, rather than the entire formula; 3. It can be customized in combination with CSS, usually displayed in italics by default; 4. Avoid confusion and cannot be used in JavaScript variables. This tag improves the readability and barrier-free access of content, and is suitable for technical documents, tutorials and other scenarios.

- How to create a responsive image gallery with CSS?
- Using CSSGrid is the best way to create a responsive image library. 1. Use CSSGrid layout to implement adaptive grids through display:grid, grid-template-columns:repeat(auto-fit,minmax(200px,1fr)) and gap; 2. Optionally add media queries to accurately control the number of columns at different breakpoints, such as the small screen set to 1 column and the flat panel set to 2 columns; 3. Optimize image performance, adjust the size reasonably, use WebP format and combine srcset to achieve responsive loading; in addition, you can try multi-column layout to simulate the waterfall flow effect, but it is recommended to use the main Grid solution, which does not require JavaScript, is highly adaptable and dimensional.

- Using flexbox and overflow-x:auto is the best way to create horizontal scrolling areas. 1. Set container display:flex and overflow-x:auto to enable horizontal scrolling; 2. Use flex:00auto to prevent child elements from scaling; 3. Set fixed width such as width:200px to ensure consistent item size; 4. Add gap or margin to provide spacing; 5. Optional scroll-snap-type and scroll-snap-align to achieve scroll adsorption; 6. Enhance visual effects by hiding vertical scroll bars; 7. It is recommended to use flexbox instead of white-space:nowrap, because
