- CSS selector nesting: use preprocessor to improve style management efficiency
- This article explores the necessity of CSS selector nesting and its limitations in native CSS. For complex HTML structures and duplicate style definitions, native CSS cannot directly support selector nesting, resulting in verbose code. The core solution is to use CSS preprocessors such as SASS/SCSS or LESS, which provide powerful nested syntax, can greatly simplify the writing and maintenance of style sheets, and generate standard CSS through compilation.

- Master Flexbox layout in React: Solve the problem of vertical stacking of map elements
- This tutorial is designed to solve common layout problems when dynamically rendering list items in React applications: When elements are expected to be arranged horizontally, they appear to be stacked vertically. We will dig into the cause of this problem and demonstrate how to apply the display:flex style to the parent container of the list item through the correct application of the Flexbox layout, ensuring that the mapping elements can be displayed in rows as expected, achieving a clear and responsive interface layout.

- JavaScript: How to prevent the keyboard from automatically hiding when clicking non-input elements
- This article aims to solve common user experience problems in mobile development: when the user focuses on the input box and evokes the soft keyboard, clicks other non-input elements on the page (such as custom function buttons), the soft keyboard will be accidentally hidden. The tutorial will introduce in detail how to listen to button click events through JavaScript and actively reset the focus back to the input element, thereby ensuring the continuous display of the soft keyboard and improving the smoothness of user operations.

- Solve the problem of vertical stacking of mapped elements in React: Forced items to be arranged by row
- This tutorial is designed to solve the common Flex layout problem in React applications, where elements are accidentally stacked vertically instead of arranged by row when rendering list items using map functions. The core is to understand how Flexbox works and ensure that the display: flex style is correctly applied to the parent container containing all elements to be arranged, rather than each individual child element, thereby achieving the expected horizontal layout.

- Configure Javalin to correctly render Pebble templates
- This article explains in detail how to correctly configure and render Pebble templates in Javalin applications. The core content includes: changing the Pebble template file suffix to .peb to ensure that Javalin correctly recognizes the rendering engine; placing the template file in the src/main/resources directory instead of the public static file directory; handling template rendering through routing instead of directly redirecting to the template file; and optimizing static file configuration, it is recommended to use classpath loading. Following these guidelines can prevent template display exceptions and improve application structure clarity and security.

- CSS selector nesting: Use preprocessor to improve style management efficiency
- Modern CSS natively does not support selector nesting, resulting in redundant repetition of parent selectors when dealing with complex or duplicate child element styles. This article will introduce how to use Sass, Less and other CSS preprocessors to implement selector nesting, thereby greatly simplifying style code, improving readability, maintenance and development efficiency, and providing detailed examples and best practices.

- Use Tailwind CSS to achieve smooth transition of element width when hovering (2 seconds)
- This tutorial is intended to explain in detail how to use Tailwind CSS to achieve smooth width transitions when mouse over using elements (especially elements in elastic layouts) and specify a transition duration of 2 seconds. The article will introduce two main methods: pure Tailwind tool class scheme, using flex-initial and hover:grow to cooperate with transition classes; and using @layer utilities to define custom CSS classes for more granular control. Use sample code and precautions to help readers easily master the skills of creating dynamic interactive interfaces.

- Dynamic form element tag association strategy in React/JSX
- In React or JSX environments, it is a common challenge to correctly associate labels for multiple form elements generated dynamically (such as input boxes) because the id attribute of HTML must be globally unique. This article will explore two main solutions: explicitly passing unique IDs through component properties (props), and automatically generating unique IDs inside components, aiming to ensure the semantics, accessibility, and SEO-friendliness of forms.
