  • Sass vs vanilla CSS tutorial for developers
    Sass vs vanilla CSS tutorial for developers
    It is worth learning Sass because it can significantly improve the efficiency and maintenance of style development. 1. The variable system is more intuitive and supports multiple data types, which facilitates the unified management of style values such as colors and fonts; 2. Nested syntax reduces duplicate selectors to make the structure clearer; 3. Mixins and functions improve style reuse capabilities and simplify complex tasks such as responsive design; 4. Compilation process needs to be configured, but modern tools are well supported. Suitable for medium and large projects, team collaboration and scenes that require theme switching.

  • How to select a parent element using CSS Selectors?
    How to select a parent element using CSS Selectors?
    CSS cannot directly select the parent element, but the target effect can be achieved indirectly with a specific selector through structural understanding. 1. Use the :has() pseudo-class (experimental) to select the parent element according to whether the child element exists, such as .container:has(.special); 2. Manually add specific class names to the parent element to achieve style control; 3. Use JavaScript to dynamically judge and add class names to respond to changes in the state of the child element.

  • Implementing advanced layouts with CSS Grid techniques
    Implementing advanced layouts with CSS Grid techniques
    To use CSSGrid to implement advanced layouts, the key is to master its structural control and positioning methods. First, use grid-template-areas to build a semantic layout, such as the "head sidebar content area bottom" structure; second, through grid-column and grid-row, the element position can be accurately controlled, so that the card can span multiple columns or rows; then, combine minmax() and auto-fit to create a responsive grid, and automatically adjust the number of columns; finally, use cascade layout and z-index to control the element level to achieve a floating effect. These techniques can address complex and responsive web design needs.
