- What is the difference between :nth-child(n) and :nth-of-type(n)?
- The core difference between :nth-child(n) and :nth-of-type(n) is the different counting methods. 1.:nth-child(n) counts in the order of all child elements, and matches only if the nth child element happens to be the target label; 2.:nth-of-type(n) counts only in the order of the same element, selects the nth child element of that type in the parent element, and ignores other types of elements. When using it, you should choose according to whether the element type needs to be considered. The former is suitable for situations where the structure is fixed and the position is required, while the latter is suitable for situations where only a specific type of element needs to be selected in mixed elements.

- What are the ::before and ::after pseudo-elements used for?
- CSS's ::before and ::after pseudo-elements are used to insert decorative content or auxiliary layouts before and after the element content. Common uses include: 1. Add decorative elements such as icons, separators or custom bullets; 2. Insert context-related text or symbols such as external link logos or chapter numbers; 3. Clear floats to solve layout problems (old technology); 4. Implement silhouettes, borders and other style effects without adding HTML tags. Both can be styled independently and used in conjunction with positioning, but content added through the content property cannot be selected or reliable access to the screen reader and should not contain critical information.

- How does the aspect-ratio property work?
- The aspect-ratio attribute of CSS is used to define the aspect ratio of an element so that it maintains a specific shape when different screen sizes or content changes. 1. Set a fixed aspect ratio through aspect-ratio:16/9; etc. If the height or content determines the height, the width will be automatically adjusted to match the ratio, and vice versa; 2. When used in combination with layout tools such as Flexbox or Grid, it is necessary to note that if the width and height are defined at the same time, this attribute may be ignored; 3. Commonly used in responsive video containers, picture placeholders and UI cards, avoid using padding techniques or JavaScript to maintain the ratio; 4. Not suitable for replacement elements with their own size, such as, and attention should be paid to old browser compatibility issues.

- How do you change the box sizing model for an element?
- To change the box model of an element, the most common method is to use the box-sizing property. 1. Set box-sizing:border-box; the element width and height can include content, padding and border; 2. All elements and pseudo-elements can be set globally through wildcard selectors to use the border-box model; 3. Note that this attribute is not inherited by child elements, and compatibility conflicts with third-party components must be considered. For example, the total width of the div under .box{width:200px;padding:20px;border:5pxsolid#333;box-sizing:border-box;} is still 200px.

- How to use RGBA and HSLA for transparency?
- RGBA is a color format based on the RGB color model and adds an alpha channel to represent transparency, while HSLA is a transparent color representation based on the HSL model and adds an alpha channel to represent transparency; 1. RGBA uses red, green and blue primary colors plus transparency values ??(0-1), such as rgba (255, 0, 0, 0.5) to represent translucent red; 2. HSLA uses hue (0-360), saturation (percentage), brightness (percentage) and transparency to define colors, such as hsla (120, 100%, 50%, 0.3) to represent green and have a transparent effect; 3. Both can be used for background, text, border and other style settings, and will not affect the transparency of other parts of the element; 4. In contrast, HSL

- What is CSS Grid Layout?
- CSSGrid is a two-dimensional web layout tool that allows developers to accurately control the position and size of page elements by defining rows and columns. Unlike Flexbox, it can handle rows and columns simultaneously, suitable for building complex structures. To use Grid, you must first set the container to display:grid, and define the row and column size through 1.grid-template-columns and 2.grid-template-rows, set the spacing, and 4.grid-template-areas named area to improve readability. Its typical application scenarios include responsive layouts, dashboard interfaces, and picture galleries. Practical tips include: 5. Use grid-column/g
