Article Introduction：The H5 page can achieve animation effects. Common animation methods include CSS3 animation and JavaScript animation library. CSS3 animations are suitable for simple effects, such as element movement and rotation; the JavaScript animation library is powerful and can achieve dynamic effects, such as particle effects and easing animations. The choice of JavaScript animation library requires consideration of requirements and technical level. GSAP is a popular JavaScript animation library that provides rich APIs to easily create complex animations. To optimize animation performance, frequent DOM operations should be avoided, CSS animations should be used reasonably, and requestAnimationFrame and cache should be considered, and the code should be kept clean and structured and annotated.

Article Introduction：Web standards and technologies have evolved from HTML4, CSS2 and simple JavaScript to date and have undergone significant developments. 1) HTML5 introduces APIs such as Canvas and WebStorage, which enhances the complexity and interactivity of web applications. 2) CSS3 adds animation and transition functions to make the page more effective. 3) JavaScript improves development efficiency and code readability through modern syntax of Node.js and ES6, such as arrow functions and classes. These changes have promoted the development of performance optimization and best practices of web applications.

Article Introduction：There are two ways to add JavaScript to HTML: write JS directly in HTML or introduce external JS files. 1. Writing JS directly is suitable for simple scripts or tests, wrapping code with tags, it is recommended to put it in front, or in the defer/async attribute to avoid blocking rendering; 2. External JS files are more common, and are introduced through src to separate HTML and JS, which is convenient for maintenance and reuse; 3. Use async or defer to improve performance. Async is used for scripts that do not rely on DOM, and execute after loading, and then execute in order after defer and other HTML parsing is completed; 4. It is recommended to put scripts in front, if you use defer/async, you can put them, but avoid inserting them into the middle of the body to avoid affecting the rendering stream

Article Introduction：CSS3 special effects improve development efficiency, but also affect performance. This article introduces a bookmarking tool called CSS Stress Test, which can help developers identify CSS code that causes website performance problems. The background, rounded corners, shadows, transparency and transformation of CSS3 greatly simplifies the web development process and avoids the use of image slicing, extra elements or scripts. However, these features can also have a significant impact on browser performance. A few years ago, when I first tried these technologies, I was stunned by the impact on browser performance. A simple CSS property can lead to obvious redrawing and page scrolling stuttering. In one project, I had to give up rounded corners and use pictures to solve performance problems. Fortunately, beauty

Article Introduction：When learning JavaScript from zero foundation, you should start with practice and write running code first to cultivate interest. The specific steps include: 1. Starting from a small HTML JS project, mastering basic DOM operations; 2. Disassemble and practice basic syntax such as variables, conditional judgment, loops, functions, etc.; 3. Learn to use console.log() and developer tools to debug code; 4. Complete simple tasks to build confidence, such as judging age, traversing arrays, and displaying object information; 5. Consider the learning framework after a solid foundation. The focus is on more hands-on, less theory, and promote the learning process through a sense of accomplishment.

Article Introduction：Both Callbacks and promises are used to handle asynchronous operations in JavaScript, but they differ significantly in readability and maintainability. 1. Callbacks are functions passed as parameters, suitable for simple or old environments, but when nested for a long time, it is easy to cause "callback hell". 2. Promise improves code clarity and error handling capabilities through .then() and .catch() chain calls, suitable for complex logic and modern JS features. 3. Use suggestions: Select callbacks for small scripts or old browsers; select Promise when complex asynchronous logic or async/await, and convert callbacks to Promise through encapsulation to improve compatibility.

Article Introduction：There are three main ways to execute PHP code online. 1. Use an online PHP editor (such as 3v4l.org, onlinephp.io, JDoodle) to directly write and run scripts, which is suitable for temporary testing and teaching demonstrations; 2. Use multi-language online IDEs (such as Replit, paiza.IO) that support HTML/CSS/JS, which are suitable for testing front-end and back-end interaction functions, but pay attention to platform configuration restrictions; 3. Use cloud servers or sandbox environments (such as Codeanywhere, Gitpod), which is suitable for testing complex functions such as database connections, which require registration and have certain usage thresholds. Simple test recommended online editor, complete project recommended local environment.

Article Introduction：H5WebAssembly makes porting game engines to the web page efficient and practical because their performance is close to native and can interact seamlessly with JavaScript. Its core advantages include high execution efficiency, fine memory control, and cross-platform compatibility; better performance than asm.js, supports reuse of C/C code bases, and simple deployment without plug-ins. Common challenges in porting are: 1. The graphics API does not support WebGL/WebGPU, and use it instead; 2. The file system is restricted and requires a virtual file system or IndexedDB; 3. The thread support is unstable and needs to be handled with caution; 4. Audio and input events need to be bridged through JS. The recommended steps to start the porting are: 1. Use the Emscripten toolchain; 2. Verify from small modules

Article Introduction：Core points Bookmark applets are small JavaScript code embedded in browser bookmarks that enhance the functionality of a web browser and simplify the workflow of web developers. Bookmark applets have a wide range of uses, ranging from simple navigation tasks to more complex operations, such as modifying page content, analyzing page structure, and even automating tasks on the website. While bookmark applets are generally safe and reliable, they can cause namespace conflicts. This problem can be avoided by creating anonymous functions with its own variable scope as bookmark applets. For complex bookmark applets, there is a way to bypass the length limit of bookmarks in some browsers. The actual bookmark applet implementation can be used as external .js
