- css container queries example
- CSSContainerQueries allows components to respond to changes based on their container size rather than viewports, solving the limitations of traditional media queries in component development. ① By setting container-type:inline-size or abbreviated container:card/inline-size, define the parent element as a query container and can be named; ② Use the @containercard(min-width:400px) syntax to apply styles when the container width reaches the specified conditions, so as to switch the card from vertical layout to horizontal layout; ③ This mechanism enables the same component to be adaptively displayed in different containers, suitable for grid layout, component library and CMS systems; ④

- What are user agent stylesheets?
- User agent stylesheets are the default CSS styles that browsers automatically apply to ensure that HTML elements that have not added custom styles are still basic readable. They affect the initial appearance of the page, but there are differences between browsers, which may lead to inconsistent display. Developers often solve this problem by resetting or standardizing styles. Use the Developer Tools' Compute or Style panel to view the default styles. Common coverage operations include clearing inner and outer margins, modifying link underscores, adjusting title sizes and unifying button styles. Understanding user agent styles can help improve cross-browser consistency and enable precise layout control.

- What is the difference between `text-decoration` and `text-decoration-line`?
- Text-decoration and text-decoration-line are different. The former is an abbreviation attribute used to set line types, colors and styles at the same time, which is suitable for defining all styles at once; the latter is only used to specify line types, which is suitable for controlling the line types without affecting the color or style. 1. Text-decoration can combine the line types, styles and colors, suitable for quick reset or custom link styles; 2. Text-decoration-line only controls the type of line, suitable for overlaying effects or retaining the default style details; 3. Using text-decoration may overwrite the settings of text-decoration-line because

- What is the purpose of vendor prefixes?
- CSSvendorprefixes exist to allow browsers to experimentally support and avoid compatibility issues before CSS features become standard. Its core functions include: 1. Enable developers to test new features in advance; 2. Enable browser manufacturers to improve implementation without destroying existing websites; 3. Wait for the standard to stabilize before adopting unified syntax. Common prefixes are such as -webkit- (Chrome, Safari), -moz- (Firefox), -ms- (IE, old version of Edge), -o- (old version of Opera). Nowadays, most projects are automatically processed using tools such as Autoprefixer, without manual addition, only when old projects that need to be compatible with extremely old browsers and maintain old projects without build tools

- What is CSS-in-JS?
- CSS-in-JS is a method of writing CSS styles directly in JavaScript or TypeScript code. 1. It avoids global conflicts by defining styles within components; 2. Use libraries such as styled-components or Emotion to support dynamic styles, pseudo-classes and media queries; 3. Provide scope styles, dynamic customization, code co-location and theme support; 4. However, there is runtime overhead, package size increase, SSR complexity and learning costs; 5. Applicable to complex and dynamic React applications, but traditional CSS or Tailwind may be better in simple projects. Therefore, CSS-in-JS provides a powerful component style solution, but requires trade-offs on performance and complexity

- How to overlap elements in CSS?
- To achieve CSS element overlap, you need to use positioning and z-index attributes. 1. Use position and z-index: Set elements to non-static positioning (such as absolute, relative, etc.), and control the stacking order through z-index, the larger the value, the higher the value. 2. Common positioning methods: absolute is used for precise layout, relative is used for relatively offset and overlap adjacent elements, fixed or sticky is used for fixed positioning of suspended layers. 3. Actual example: By setting the parent container position:relative, child element position:absolute and different z-index, the card overlap effect can be achieved.
