- How to create a multi-column layout in CSS?
- There are three common ways to implement CSS multi-column layout: 1. Use columns attribute, suitable for automatic column division of text content, simple and efficient, but cannot accurately control the content of each column; 2. Use Flexbox, suitable for horizontal arrangement, flexible control but requires manual width calculation; 3. Use CSSGrid, suitable for complex layout, powerful functions but high learning costs. The selection method should be determined based on the content type and layout requirements.

- Explain the descendant combinator (space)
- The descendant selector is connected through spaces to select all descendant elements that meet the criteria within an element. For example, nava{color:red;} means that all a elements in nav are selected, regardless of the depth of the nesting level. It is different from the child selector (>) adjacent sibling selector ( ) and general sibling selector ( ~ ), and corresponds to different levels or positional relationships respectively. When using it, you need to pay attention to scope control, performance impact and naming conflict issues. You can optimize the application by limiting the selector hierarchy, avoiding excessive nesting, and improving the selector accuracy. In practice, descendant selectors can be used to implement regional style management, such as .sidebara or .post-contentimg, etc.

- How to select an element by its text content in CSS?
- ?Pure CSS cannot select elements based on text content, because the CSS standard does not support text content-based selectors such as: contains(); ? Classes or attributes should be used to accurately locate elements, which is a semantic and efficient approach; ? If you have to choose according to text, you can use JavaScript or jQuery to implement it; ?? Although modern browsers support the pseudo-class of: has(), it cannot directly match the plain text content and can only be indirectly matched through child elements or attributes. Therefore, the best practice is to reasonably use the principle of separation of HTML structure and style.

- How to add a box shadow in CSS?
- Use the box-shadow attribute to easily add shadows, and its syntax is box-shadow:offset-xoffset-yblur-radiusspread-radiuscolor; 1. In the basic usage, only the first two values need to be specified, the rest are optional; 2. Use the inset keyword to create inner shadows; 3. You can add multiple shadows by comma separation; it is recommended to use rgba() to achieve transparent effect. The larger the blur radius, the softer the shadow. The extended radius can expand or narrow the shadow range. The box-shadow does not affect the layout and is widely supported, but excessive use on animation elements should be avoided to maintain performance.

- css flexbox wrap example
- Flex-wrap attribute is used to control whether child elements in the Flex container will be wrapped when there is insufficient space. Its commonly used values are nowrap (there is no line wrapping by default), wrap (the line wrap is allowed, the next line is below), and wrap-reverse (the line wrap is allowed, the next line is above); in the responsive card layout example, automatic line wrapping is achieved by setting flex-wrap:wrap, combined with flex:00calc (33.33%-16px) to ensure that each line displays up to 3 fixed-width cards and subtracts the spacing. Use the gap attribute to uniformly control the distance between cards, and then adjust the flex-basis to calc (50%-16px) (2 per line) under the small screen through media query and adjust the flex-basis to calc (50%-16px) (2 per line) and
