  • What is the :target pseudo-class and how can it be used?
    What is the :target pseudo-class and how can it be used?
    CSS's :target pseudo-class is used to style the target element based on the URL fragment identifier. It works by the browser scrolling to the element when the URL contains a # symbol and element id and allows a specific style to be applied to the element via :target. Common use cases include highlighting the page section after navigation, creating tabs or slideshows without JavaScript, and improving accessibility to long pages. Usage tips include ensuring that id is unique, combining transition or animation effects, switching content visibility with display attributes, and considering compatibility with older browsers.

  • When should you use rem units over em units?
    When should you use rem units over em units?

Avoid the problem of size overlay during nesting; 3. Suitable for setting global spacing and layout; 4. Em is suitable for scenes that require local scaling, such as buttons, labels or designs that focus on layout proportions.

  • Can you nest a Flexbox container inside a CSS Grid item?
    Can you nest a Flexbox container inside a CSS Grid item?
    Yes, you can use Flexbox in CSSGrid items. The specific approach is to first divide the page structure with Grid and set the subcontainer into a Grid cell as a Flex container to achieve more fine alignment and arrangement; for example, nest a div with display:flex style in HTML; the benefits of doing this include hierarchical layout, easier responsive design, and more friendly component development; it is necessary to note that the display attribute only affects direct child elements, avoids excessive nesting, and considers the compatibility issues of old browsers.

  • What is a CSS animation defined with @keyframes?
    What is a CSS animation defined with @keyframes?
    @keyframes is used in CSS to create keyframe animations, allowing developers to define the styles of elements at different stages of the animation. 1. Specify the style of each stage of the animation through percentage or from/to, such as 0%, 50%, and 100% respectively representing the start, middle and end states respectively; 2. Use the animation attribute to apply the defined keyframe animation to elements, including setting the animation name, duration, speed function, delay and number of playbacks, etc.; 3. Commonly used to implement complex custom animation effects, such as loading indicators, hover effects, UI feedback and background animation; 4. Notes include ensuring that the start and end frames are included, avoiding layout jitter caused by animation, testing browser compatibility, and using animation

  • How to use the :nth-child() pseudo-class?
    How to use the :nth-child() pseudo-class?
    :nth-child() pseudo-class is used in CSS to accurately select specific child elements based on element position. Its basic syntax is element:nth-child(n), which can select the nth child element, and supports odd, even and an b formulas, such as 2n 1 or n 3, respectively, to realize odd line selection or custom interval and starting point. For example, tr:nth-child(even) adds background color to even rows of the table. Unlike :nth-of-type(), :nth-child() calculates all child elements, while the former only calculates the same element. Common uses include zebra pattern tables, gallery layouts, navigation menus and form typesettings. When using them, you need to use them flexibly in combination with specific HTML structures.

  • How to style a link based on its state (:link, :visited, :hover, :active)?
    How to style a link based on its state (:link, :visited, :hover, :active)?
    In web development, the style of linking different states can be individually set through the pseudo-class of CSS to improve the user experience. 1. First understand the meaning of each pseudo-class::link means no link is visited, :visited means the link has been visited, :hover means the hover state, and :active means the instant of clicking; 2. Writing pseudo-classes in LVHA order ensures the correct priority, and the order should be: link, :visited, :hover, :active; 3. Style suggestions include avoiding the use of similar colors to distinguish states, combining text decoration to enhance recognition, and pay attention to the differences in behavior of mobile:hover; 4. When considering accessibility, it is recommended to add: focus status to support screen reader users to ensure link gathering
