Article Introduction：The page switching effect can be achieved through the combination of CSS3 and JavaScript. The specific steps are: 1. Use CSS to define transition styles, such as transition or animation attributes to control page entry and exit animation; 2. Dynamically add or remove class names during page switching through JavaScript to achieve animation triggering and content updates; 3. Pay attention to optimization of performance, avoid layout jitter, and reasonably use hardware acceleration and resource preloading. In addition, you can also use global containers to manage transitions uniformly, use CSS variables to improve flexibility, and set diversified animations for different pages, so as to achieve rich and smooth page switching effects while ensuring user experience.

Article Introduction：CSS's :target pseudo-class is used to match and style target elements in the page based on the URL's fragment identifier (last part). 1. It is often used to highlight the page area that users jump to through anchor links, such as highlighting the target section through background color or border; 2. It can be used for simple tab pages or accordion effects without JavaScript, and control the display and hiding of the target elements through display attributes; 3. It can combine transition to achieve smooth animation effects when target switching; 4. It only takes effect when the URL fragment matches the element id, and does not affect the browser's default scrolling behavior, and is not supported but elegantly downgraded in old browsers such as IE8 and below.

Article Introduction：requestAnimationFrame (rAF) is more suitable for animation than setTimeout or setInterval because it is synchronized with the browser refresh mechanism to achieve smoother and more efficient animation effects. ① rAF will call the specified function before the next repaint of the browser, usually execute at a frequency of 60 frames per second to make the animation smoother; ② When the tab page is not in the foreground, it will automatically pause and save resources; ③ When using it, start the animation loop by recursively calling requestAnimationFrame and stop avoiding memory leaks under appropriate conditions; ④ Pay attention to avoid frequent operation of DOM, it is recommended to use high-performance properties such as transform and use the timestamps received by the callback function for precise control; ⑤

Article Introduction：CSS's :target pseudo-class is used to style the target element based on the URL fragment identifier. It works by the browser scrolling to the element when the URL contains a # symbol and element id and allows a specific style to be applied to the element via :target. Common use cases include highlighting the page section after navigation, creating tabs or slideshows without JavaScript, and improving accessibility to long pages. Usage tips include ensuring that id is unique, combining transition or animation effects, switching content visibility with display attributes, and considering compatibility with older browsers.

Article Introduction：The key to making interactive HTML prototypes is to master the coordination of structure, style and behavior. 1. Use basic HTML to build structures, such as buttons and pop-up elements; 2. Use CSS to control state changes, replace frequent DOM operations through class switching, improve debugging efficiency; 3. Use native JS to achieve simple interaction, such as clicking to show or hide elements, keep the code lightweight; 4. Add animation effects to improve the experience, such as pop-ups fade in and out, but avoid excessive complexity. Through these steps, you can quickly verify ideas and demonstrate a clear process.

Article Introduction：View conversion in Astro: A sharp tool for smooth page switching This article is excerpted from SitePoint Premium's book "Unleashing the Power of Astro", which introduces the view conversion function in Astro. The View Transformation API provides a convenient way to simultaneously update DOM content in a single operation and generate animation conversion effects between individual DOM states. Implementing this on the web in the past was very difficult, but with this new API, the transformation became fairly easy. Research shows that using the view conversion API can speed up the perceived performance of a website. Astro natively supports view conversion and has built-in fallback mechanism to support the A is not currently supported.

Article Introduction：CSS transitions enable switching between CSS attribute values ??through smooth animations, which are suitable for user interaction scenarios such as button hovering effects, menu expansion and collapse. Common usages include button closure effect, drop-down menu gradient, background color gradient, image transparency or zoom changes. The basic syntax is a transition: attribute duration time sequence function, which can specify a single or multiple attributes, or all can be used to represent all attributes, but it should be used with caution. Timing functions such as ease, linear, and ease-in-out control the animation speed curve, and can also be customized by cubic-bezier. It is recommended to prioritize opacity and transform for better performance, combined with @media(prefers-

Article Introduction：There are three main ways to fix the head of a web page: 1. Use position:sticky is the most common and lightweight method. It needs to be used with the top value and avoid the parent container having properties such as overflow:hidden or transform; 2. Use position:fixed to make the head completely fixed to the top, but pay attention to content occlusion. It is recommended to add margin-top to the main content and test the performance of different devices; 3. Combined with JavaScript, more complex logic can be implemented, such as switching to fixed states after scrolling for a certain distance or adding animation effects, which is suitable for dynamic interactive scenarios. Just choose the right method according to your needs.

Article Introduction：There are three ways to embed HTML5 in SVG: inline SVG, img tag references and CSS links. Inline SVG allows style and interaction control, suitable for small icons or dynamic graphics; img tags are simpler but restrict interaction, suitable for independent illustrations; CSS backgrounds are suitable for layout elements but not for dynamic content. SVG can use CSS or JavaScript for style design and animation effects, and need to add ARIA attributes to improve accessibility, such as role="img" and aria-label. When optimizing, use SVGO to clean up redundant data, avoid embedding fonts, and ensure that the viewBox attribute is correct for responsive scaling. Mastering these techniques can help create flexible and beautiful
