What are the difficulties in making H5 pages

Difficulties in H5 page production include: mastering the characteristics of HTML, CSS, and JavaScript, especially for mobile browsers; animation and interaction design, you need to be proficient in CSS and JavaScript animation libraries, and pay attention to user experience; cross-platform compatibility, understand the support differences between different browsers and operating systems; performance optimization, and make good use of lazy loading, code segmentation and other technologies to improve page loading speed.

H5 page production: those points that drive you crazy

Many friends think that making H5 pages is very simple, isn’t it just dragging and dragging? wrong! A big mistake! It looks simple on the surface, but in fact it is so pitfalls that you doubt your life. In this article, let’s take a look at the difficulties in making H5 pages, as well as the lessons I have learned from years of hard work. After reading it, you will be able to more clearly understand the complexity of H5 development and avoid falling into common pitfalls.

Let’s talk about the basics first: Do you think you understand HTML, CSS and JavaScript?

Many novices think that if you master these three things, you can get H5. In fact, this is just the first step in the Long March. You have to understand their characteristics in depth, especially their performance in mobile browsers. A page that works perfectly on a desktop browser may cause various deformations, misalignment, or even crashes directly on the phone. This involves a series of issues such as responsive design, adapting to different screen sizes, different operating systems, etc. You have to learn to use media queries ( @media ) to gracefully handle various screen sizes, use Flexbox or Grid layouts to flexibly control the arrangement of page elements, and also consider the compatibility issues of different browsers. Don’t forget that the performance bottleneck on the mobile side is more significant than that on the desktop side, and the efficiency of the code directly affects the user experience.

Core: Those crazy details

Animation and Interaction: This part is the soul of H5 page making and one of the most difficult parts. Do you think simple animation effects are easy to implement? wrong! You need to be proficient in CSS animations and JavaScript animation libraries (such as GreenSock, Anime.js), and also consider the performance of animations to avoid lag. Interaction design tests your skills. A good interaction design can improve the user experience to a higher level, and otherwise it will drive users crazy. This requires you to have a deep understanding of the user experience and be able to skillfully use various interactive skills.

Cross-platform compatibility: Different browsers and operating systems have different levels of support for H5, which leads to cross-platform compatibility issues. A page that works perfectly on Chrome may have various problems on Safari or IE. You need to master various browser compatibility skills, such as using CSS preprocessors (Sass, Less) to improve code maintainability, and using the automatic prefix tool (Autoprefixer) to automatically add browser prefixes.

Performance optimization: The performance of mobile devices is limited, and the H5 page needs to be optimized to ensure smooth operation. This includes code optimization, image compression, resource load optimization, etc. You need to learn various performance optimization techniques, such as using lazy loading, code segmentation, caching and other technologies to improve page loading speed.

A simple example, feel the difference in performance:

 <code class="javascript">// 低效的动画实现，大量重复计算function animateInefficiently(element, duration) { let startTime = null; function step(timestamp) { if (!startTime) startTime = timestamp; let progress = (timestamp - startTime) / duration; if (progress </code>

This code shows two ways to implement animations. The first method is inefficient, and the second method is inefficient with CSS animation, which is more efficient. In actual development, you need to carefully weigh the performance differences of various implementation methods and choose the optimal solution.

Debugging Tips and Best Practices

Debugging H5 pages is a headache. You need to master various debugging techniques, such as using browser developer tools to debug JavaScript code, and using Charles or Fiddler to capture packets and analyze network requests. At the same time, you need to develop good programming habits, such as writing highly readable code, writing unit tests, using version control tools, etc., which can effectively improve development efficiency and code quality.

H5 page production is much more complicated than you think, but as long as you master the necessary skills and skills, you can easily deal with various challenges and create amazing H5 pages. Remember, details determine success or failure! Don’t be lazy and take every detail seriously, so that you can become a real H5 big shot.
