Article Introduction：Event delegation is a technique that uses the event bubble mechanism to hand over the event processing of child elements to the parent element. It reduces memory consumption and supports dynamic content management by binding listeners on parent elements. The specific steps are: 1. Binding event listeners to the parent container; 2. Use event.target to determine the child elements that trigger the event in the callback function; 3. Execute the corresponding logic based on the child elements. Its advantages include improving performance, simplifying code maintenance and adapting to dynamically added elements. When using it, you should pay attention to event bubble restrictions, avoid excessive centralized monitoring, and reasonably select parent elements.

Article Introduction：AVIF and WebP are both preferred formats for modern web image optimization, but the applicable scenarios are different: 1. AVIF compression efficiency is higher, the files are smaller, and it supports HDR and wide color gamut, which is suitable for modern browser environments that pursue extreme compression and high-quality; 2. WebP has wider compatibility, faster encoding, and mature tool chains, which are suitable for scenarios that need to support old browsers or medium optimization needs; 3. It is recommended to use labels to combine both, give priority to using AVIF and downgrading to WebP, and JPEG/PNG is the final backup to achieve a balance of compatibility and performance; 4. AVIF is preferred for high-traffic media websites or bandwidth-sensitive scenarios, while content-based websites can continue to be dominated by WebP; 5. Automatic distribution of CDN formats can simplify deployment. In summary, it should

Article Introduction：The key to responsive design is to reasonably divide breakpoints and adjust the styles in a targeted manner. 1. Understand the basic structure of media query, use @media plus conditional judgment, such as setting styles according to screen width; multiple conditions can be combined to adapt to different devices. 2. Setting reasonable breakpoints should be based on content and design drafts. It is recommended to gradually adapt to large screens starting from the mobile terminal. Common reference values ??include vertical screen max-width:767px for mobile phones, vertical screens on tablets, and above 1023px for desktop browsers. 3. To modify the key styles in a targeted manner, you only need to adjust the parts that really need to be changed, such as layout switching, font size, image button size, element display and hidden. 4.
