  • Understanding and using CSS Container Queries (emerging topic)
    Understanding and using CSS Container Queries (emerging topic)
    CSSContainerQueries is a new responsive design mechanism that allows restyling based on the size of component containers rather than viewport size. The steps to use are: 1. Define the container type through container-type, such as inline-size or size; 2. Optionally use container-name to name the container; 3. Use @container query to write corresponding style rules. Applicable scenarios include cards, toolbars, advertising modules, and other components that need to be adaptively displayed in different contexts. Notes include explicit declaration of container type, performance impact and compatibility issues. Currently, mainstream browsers have supported it but need to combine downgrade processing or progressive enhancement strategies.

  • When should you use !important and what are its implications for CSS Selectors specificity?
    When should you use !important and what are its implications for CSS Selectors specificity?
    Use !important should override styles that cannot be modified directly, such as third-party or uncontrollable inline styles, if necessary. 1. Applicable scenarios: inline styles injected by CMS or framework, third-party styles that cannot be rewrited later, and quick coverage during browser debugging. 2. Influence mechanism: mandatory rules are preferred, breaking the normal specificity level. If both parties use it, return to normal specificity judgment. 3. Potential risks: Increase debugging difficulty, reduce maintenance, and encourage bad habits, leading to more important superposition to form chaos. 4. Best practices: only use when there is no other solution, add comments to explain the reasons, avoid large-scale project abuse, and prioritize testing of non-important solutions. The overall CSS strategy should be examined when used frequently.

  • Styling Variable Fonts using CSS properties
    Styling Variable Fonts using CSS properties
    To use CSS attributes to control variable font styles, you need to master four core methods. 1. Use font-weight to set the numerical values ??from 1 to 1000 to finely control the word weight, such as p{font-weight:450;}; 2. Use font-stretch to adjust the font width in percentage, such as .title{font-stretch:110%;}; 3. Use font-style to combine font-variation-settings to achieve tilt or custom axis adjustment, such as .emphasis{font-variation-settings:"slnt"20;}; 4. Combine multi-axis parameters

  • How to create responsive typography?
    How to create responsive typography?
    The key to responsive typography is to establish flexible rules to adapt to different devices. Use relative units such as rem or em to replace px, and facilitate conversion with html{font-size: 62.5%;}; set key breakpoints (such as 768px and 1024px) to manually adjust the font size, line height and spacing; control the line height to 1.4~1.6 times of the font, and reasonably set the paragraph spacing; allow the user's viewport to zoom, avoid forced restrictions; maintain the default viewport settings and ensure that the minimum font is not less than 16px, thereby improving reading comfort under multiple devices.

  • What are CSS preprocessors like Sass or Less?
    What are CSS preprocessors like Sass or Less?
    CSS preprocessors such as Sass and Less make CSS easier to maintain by introducing variables, nesting, and mixing features. 1. Variables can store colors, font sizes and reused; 2. Mix them into CSS code blocks that allow you to define reusable; 3. Nesting and improving HTML structure visualization, suitable for multi-file complex projects. Both need to be compiled into standard CSS, Sass supports .scss and .sass, and Less uses .less. Sass syntax is more flexible, and Less relies on JavaScript to process. Despite the rise of modern CSS and CSS-in-JS, preprocessors can reduce duplicate code and remain modular in medium and large projects, especially for teams without complex build systems or custom framework themes.

  • Can you chain multiple pseudo-classes together?
    Can you chain multiple pseudo-classes together?
    Yes, pseudo-classes can be used in combination. CSS allows multiple conditional matching by writing multiple pseudo-classes continuously, such as a:hover:visited; but the order is crucial, especially for linking pseudo-classes. The correct order is: link, :visited, :hover, :active; common scenarios include li:nth-child(odd):hover and input:invalid:focus; attention should be paid to logical conflicts, readability and maintenance issues.

  • What is the adjacent sibling combinator ( )?
    What is the adjacent sibling combinator ( )?
    To use CSS to select adjacent sibling elements that follow a particular element, the adjacent sibling combination character ( ). The core points are as follows: 1. The selector only selects the next sibling element that follows the specified element under the same parent element; 2. The element must have the same parent and is directly adjacent to the HTML structure; 3. Unlike the ~ selector, it does not match the non-direct subsequent sibling elements; 4. It is often used for the first paragraph, form style adjustment or layout spacing setting after styling the title; 5. Note that the elements must share the parent container, the order must be immediately adjacent, and the selector does not match forward or is affected by whitespace characters.

    How to create a staggered animation effect on a list of items?
    To achieve the staggered animation effect of list items, the key is to control the animation triggering timing of each element. 1. Use CSS animation animation-delay to achieve staggered effects by setting incremental delay time for each list item; 2. Use JavaScript to dynamically set delays, suitable for dynamically generated content, and automatically add different delays to each element; 3. Use @keyframes to define animation styles to ensure that the animation effects are unified and customizable; 4. Pay attention to performance and compatibility, avoid complex animations and excessive nesting, and improve user experience.

    What is the difference between ^=, $=, and *= in attribute CSS Selectors?
    In the CSS attribute selector, the difference between ^=, $= and \*= is that the matching attribute value is different. ^[attr^="value"] matches attributes that start with a specified value, such as a[href^="https"] selects all links that start with "https"; ^[attr$="value"] matches attributes that end with a specified value, such as a[href$=".pdf"] selects all links that end with ".pdf"; ^[attr="value"] matches attribute values
