    CSS tutorial for positioning elements
    Mastering CSS positioning is the key to controlling the position of web page elements. The position attributes include static, relative, absolute, fixed, and sticky, where static is the default value and does not support offset; relative moves relative to its original position; absolute is positioned relative to the recent non-static ancestor; fixed is based on viewport positioning; sticky combines relative and fixed positioning characteristics. z-index is used to control hierarchical relationships, but is only valid for non-static positioning elements and may be restricted by the parent container. Accurate positioning also needs to be used in conjunction with margin, top/left and transform, such as margin:au

    How to debug responsive layouts in browser developer tools?
    The key to debugging responsive layouts is to utilize the browser developer tools' device emulator, media query checking, layout panels, and real-time editing capabilities. Use the device simulator to view page performance at different resolutions to ensure the correct layout; use the "Computed" panel to check whether the media query rules are effective and prioritized; Chrome's "Layout" panel can visualize the layout details of Grid and Flexbox; finally use the real-time editing function to test style modification and confirm the repair effect. Proficiency in these techniques can help quickly locate and solve problems in responsive design.

  • How to select an element that does not have a certain class with CSS Selectors?
    How to select an element that does not have a certain class with CSS Selectors?
    In CSS, use:not() to negate the pseudo-class to select elements that do not contain specific class names, such as button:not(.primary) to select buttons that are not.primary; multiple exclusions need to be written in chains, such as button:not(.primary):not(.secondary); in JS, the same effect can also be achieved through querySelectorAll; it can also be used in combination with attributes and IDs, such as input:not([disabled]) or div:not(#header); it cannot be used in nested and has minimal performance impact.

    CSS tutorial on best practices for performance
    To improve web page loading speed, optimize CSS writing, including: 1. Reasonably organize and streamline CSS files, split them according to modules and merge and compress them through construction tools; 2. Delete unused CSS and compress code, remove spaces and comments; 3. Avoid nesting of complex selectors, and prioritize using class names to directly locate elements; 4. Reduce hierarchy depth and avoid abuse of general selectors and attribute selectors; 5. Optimize rearrangement and redrawing, use transform and opacity to implement animations, and first leave the document stream when batch modifying styles; 6. Use media queries to optimize responsive loading, mobile priority and load corresponding styles according to the device. These practices can improve loading speed, optimize maintenance efficiency and enhance user experience.

    How to center an entire grid within the viewport?
    To make the entire grid layout centered in the viewport, it can be achieved by the following methods: 1. Use margin:0auto to achieve horizontal centering, and the container needs to be set to set the fixed width, which is suitable for fixed layout; 2. Use Flexbox to set the justify-content and align-items properties in the outer container, and combine min-height:100vh to achieve vertical and horizontal centering, which is suitable for full-screen display scenarios; 3. Use CSSGrid's place-items property to quickly center on the parent container, which is simple and has good support from modern browsers, and at the same time, it is necessary to ensure that the parent container has sufficient height. Each method has applicable scenarios and restrictions, just choose the appropriate solution according to actual needs.
