  • Understanding CSS writing modes for localization
    Understanding CSS writing modes for localization
    CSS' writing-mode is an attribute used to control the orientation of text arrangement and is crucial in multilingual website typesetting. writing-mode has three main values: horizontal-tb (default, horizontal row from left to right), vertical-rl (vertical row from right to left, often used in traditional Chinese, Japanese, etc.), vertical-lr (vertical row from left to right, sometimes used in modern Chinese). It not only affects the direction of the text, but also affects the overall layout structure. Together with the direction attribute, the direction can be set, such as rtl is used in Arabic or Hebrew; text-orientation is used to control the character orientation in vertical mode, such as upright.

  • Debugging CSS layout issues in different browsers
    Debugging CSS layout issues in different browsers
    When debugging CSS layout problems, you must first clarify the answers: common reasons include differences in default styles, inconsistent standard support, and different box model processing. There are four solutions: one uses developer tools to check element styles and box model; two uses CSSReset or Normalize.css to unify the basic styles; three uses overflow, clear attributes or clearfix techniques to deal with floating collapse; four sets box-sizing: border-box unified box model calculation method. Mastering these tips quickly locate and fix browser compatibility issues.

  • Maintaining aspect ratios with CSS padding-top hack or aspect-ratio property
    Maintaining aspect ratios with CSS padding-top hack or aspect-ratio property
    There are two ways to maintain the aspect ratio of elements in web page layout: 1. Use padding-top skills; 2. Use the aspect-ratio attribute. The padding-top method achieves proportional control through percentage calculation of placeholding, with good compatibility but complex structure, suitable for block-level elements; the aspect-ratio method is simple and intuitive, supports modern browsers, and can directly set aspect ratios, suitable for responsive design and inline elements. If you need to be compatible with old browsers, you can use fallback style in combination with featurequery.

  • Mastering CSS selectors and combinators
    Mastering CSS selectors and combinators
    How to use CSS selector and combinatorial characters well? First of all, you need to master the basic selector, including elements, classes, IDs and attribute selectors, and pay attention to details. For example, the class name can be selected and matched multiple times, and the attribute selector supports multiple matching methods. Secondly, understand four combinations: descendants (spaces), descendants (>), adjacent brothers ( ), general brothers ( ~), and correctly distinguish between usage scenarios to avoid confusion. Furthermore, be proficient in using pseudo-classes (:hover, :nth-child, :not, etc.) and pseudo-elements (::before, ::after) to improve the simplicity of the code. Finally, application techniques include avoiding too deep levels, reducing wildcard usage, and debugging selectors with the help of developer tools to improve efficiency and maintainability.

  • Why is it a good practice to avoid using IDs for styling?
    Why is it a good practice to avoid using IDs for styling?
    There are three major problems with using ID for style design: first, the ID selector is too specific and makes it difficult to overwrite; second, the ID cannot be reused to force code duplication or structural compromise; finally, modern development has better alternatives. The high specificity of ID makes style modification difficult, easily causing redundant code and!important abuse; the limitation of ID uniqueness in HTML hinders style reuse, while class selectors naturally support multi-element reuse; currently available tools such as BEM, CSS-in-JS and Tailwind provide greater flexibility and maintainability. Although IDs are useful in anchor linking or JavaScript positioning, they should be avoided for style design to ensure scalability and consistency of CSS.

  • Pros and cons of using CSS Frameworks vs. vanilla CSS
    Pros and cons of using CSS Frameworks vs. vanilla CSS
    Choosing a CSS framework or native CSS depends on project requirements and team proficiency. Using frameworks such as Bootstrap or Tailwind can speed up development with prefabricated components, especially for prototypes or time-critical projects, but requires learning naming specifications and tool patterns; while native CSS does not require additional syntax, suitable for small projects or situations where full control is required. Frameworks may cause code redundancy and need to be manually optimized to avoid performance problems, while native CSS is more flexible but is slow to develop and prone to inconsistent. In teamwork, frameworks help unify styles and simplify handovers, but over-customization can cause confusion, while native CSS is easier to debug due to its simple structure. Therefore, both have their own advantages and disadvantages, and should be based on development efficiency, customization, performance and

  • How to define a grid container and set up columns and rows?
    How to define a grid container and set up columns and rows?
    To define a grid container and set rows, use display:grid and control rows through related properties. 1. Create a grid container: add display:grid to the parent element to make its child elements a grid item; 2. Set column width: Use the grid-template-columns attribute to specify a fixed width, fr unit or automatically adjust the number of columns; 3. Set row height: Use the grid-template-rows attribute to also support fixed values, fr units and automatic adjustment; 4. Control spacing: Set the gap between rows and columns through gap, row-gap or column-gap to achieve a more flexible layout effect.

  • What are the different color value types in CSS (e.g., hex, RGB, HSL)?
    What are the different color value types in CSS (e.g., hex, RGB, HSL)?
    In CSS, common formats for defining colors are hex, RGB, and HSL, and modern specifications have added hwb, LAB, and LCH. 1. The Hex code is suitable for static colors, compact and easy to copy, but does not support transparency unless in 8-bit format; 2. RGB supports transparency and brightness control, suitable for dynamic adjustments and translucent layers; 3. HSL represents colors in hue, saturation and brightness, which is easy to create color schemes and theme systems; 4. HWB is similar to HSL but is more readable, while LAB and LCH are used for device-independent color spaces, suitable for accessibility and color mixing, but browser compatibility is limited. Select the appropriate format according to project needs and is often used in actual development.

  • Creating a full-screen background image with css
    Creating a full-screen background image with css
    To make the picture full of the screen as the background, the key is to use background-size:cover and combine positioning settings. The specific steps are as follows: 1. Set margin:0 and min-height:100vh for the body; 2. Use the background attribute to specify the image path and set it to center fixed; 3. Add background-size:cover to maintain the scale to fill the viewport; 4. If multiple pictures need to be superimposed, use multiple backgrounds and arrange them in the stacking order; 5. Pay attention to optimizing the image format, adapting to focus areas, and handling cross-domain issues to ensure performance and compatibility.

  • Creating smooth CSS transitions and animations
    Creating smooth CSS transitions and animations
    To make CSS animation smooth, you need to select the right properties, control the rhythm, and reduce rearrangement and redrawing. 1. Priority is given to using high-performance attributes such as transform and opacity to avoid frequent triggering of re-arranged width and height; 2. Reasonably set the transition time (0.2s~0.5s) and functions, such as ease-in-out or custom cubic-bezier curves; 3. Avoid layout jitter in JS, use requestAnimationFrame instead or hand it over to CSS for processing; 4. Appropriately enable hardware acceleration, such as translateZ(0), but use will-change with caution to avoid excessive memory.

  • Using ::before and ::after pseudo-elements in css
    Using ::before and ::after pseudo-elements in css
    In CSS, ::before and ::after are pseudo-elements that are used to insert additional content before and after the element content without changing HTML. 1. When using it, it needs to be matched with content attributes, supporting strings, attribute values, pictures, etc.; 2. Commonly used to add quotes, icons, and build complex graphics; 3. Note that pseudo-elements are inline by default, and display is required to adjust the width and height, and events cannot be bound; 4. Hierarchical control can be achieved in combination with positioning, and responsive design can be adapted through media queries. Mastering them can improve page expression and reduce structural redundancy.

  • Debugging css layout issues: common problems and solutions
    Debugging css layout issues: common problems and solutions
    1. The elements are not arranged as expected: Check the display attribute, clear the float or use flex instead; 2. Height collapse: add overflow:hidden or use clearfix; 3. Margin overlap: add border/padding or use flex/grid instead; 4. Width and height percentage failure: Suppose the width of the parent element or use box-sizing:border-box. These problems are mostly caused by insufficient understanding of the box model or interference with the default style. During debugging, the structure should be analyzed first and then the code should be modified.
