    CSS tutorial on multi-column layout
    To quickly achieve similar newspaper layout effects, you can use CSS multi-column layout, and the core is enabled through column-count and column-width. 1.column-count specifies the number of columns and automatically adjusts the width; 2.column-width sets the ideal column width and automatically adjusts the number of columns; 3. When using both at the same time, the browser will give priority to satisfying the width and then adjusts the number of columns. Further optimization includes: 4.column-gap sets the column spacing, default 1em; 5.column-rule adds split lines, supporting color, width, and style abbreviations. Cross-column content processing: 6.break-inside:avoid prevents internal disconnection of elements; 7.break-before

  • What is the purpose of a CSS reset vs. a normalize stylesheet?
    What is the purpose of a CSS reset vs. a normalize stylesheet?
    CSS reset provides full control by removing all default browser styles, while Normalize corrects the differences while retaining useful defaults. 1. CSS reset resets the style to eliminate inconsistencies, which is suitable for highly customized UI; 2. Normalize smooths browser differences and retains readability and availability, suitable for projects that focus on usability and accessibility; 3. Choice depends on requirements: Reset needs to be fully controlled, defaults need to be retained and Normalize is uniformly used; 4. Some developers use it in combination, and then reset locally. The core difference between the two is that Reset starts from scratch, and Normalize fixes already have problems.

  • Which CSS properties are best to animate for performance?
    Which CSS properties are best to animate for performance?
    To achieve high performance of web animation, you should give priority to using transform and opacity attributes to avoid triggering publishing reordering attributes. 1. Transform (such as translate, scale, rotate) and opacity changes are usually accelerated by GPU, only synthesis operations are required, and no release layout or redrawing is triggered; 2. Avoid animations such as width, height, top, left, etc. layout related attributes to prevent release layout jitter; 3. You can appropriately use will-change or translateZ(0) to improve elements to independent layers, but not too many; 4. Control the complexity of animation, reduce the number of animation elements at the same time, and prefer CSS transition rather than JavaScr

    How do you perform a case-insensitive attribute match with CSS Selectors?
    Standard CSS selectors do not support direct case-insensitive property matching, but can be implemented by combining multiple selectors or using the :is() pseudo-class. The article proposes three methods: 1. Explicit matching by listing all possible case forms such as [data-type="product"] and [data-type="Product"]; 2. Use the simplified syntax of the pseudo-class to improve readability, such as: is([data-type="product"],[data-type="Product"]); 3. For dynamic content, you can use the help of
