The performance of H5 pages involves all aspects, including: HTML structure, CSS style, JavaScript interaction, as well as performance optimization and best practices. In H5 code, HTML is responsible for structure, CSS is responsible for style, and JavaScript is responsible for interaction. Optimization technologies include image compression, code optimization, caching strategies, etc. to ensure user experience. In short, the H5 effect is a systematic project that requires comprehensive consideration of design, code, performance and other aspects.

How does the H5 page production effect reflect? This question is awesome!

This cannot be explained clearly in one sentence or two sentences. To put it bluntly, the effect of H5 page is user experience, and this experience is in all aspects and cannot be measured by a single indicator. You have to look at it from the user's perspective and from the technical perspective to truly understand the three flavors.

Let’s talk about the basics first. The H5 page is a web page created by the three musketeers, HTML5, CSS3 and JavaScript. If you only know how to write a <p></p> tag in HTML, how effective will it be? Therefore, to make H5 well, you must have a deep understanding of these three things. HTML is responsible for structure, CSS is responsible for style, and JavaScript is responsible for interaction. All three are indispensable, just like cooking, without seasonings, no matter how good the ingredients are, they are useless.

The wonderful uses of HTML5: Don't think that HTML5 is just a static skeleton. It provides many new tags and APIs, such as <video></video> , <audio></audio> , <canvas></canvas> , which allow you to easily embed videos, audio, and even draw complex graphics on the page. Think about it, if a simple page suddenly plays a cool animation, will it become tall immediately?

CSS3 magic: This thing is the key to making the page beautiful. CSS3 has many characteristics, such as gradients, shadows, animations, 3D transformations, etc. If used properly, you can create various visual wonders. I once did a project and used CSS3 to create a cool 3D rotation effect, which was amazing so that customers directly added money! But don't be obsessed with it. The performance optimization of CSS3 is also very important, and it is easy to get stuck if you don't use it well. Remember, simplicity and efficiency are the king.

The soul of JavaScript: The page has structure and style, but it is still dead. JavaScript gives the page life and makes it move. You can use JavaScript to achieve various interactive effects, such as animation, form verification, data interaction, etc. A good interaction design can greatly improve the user experience. But JavaScript is also a double-edged sword. If the code is not well written, it is prone to various bugs and even affects the performance of the page. Therefore, writing efficient and elegant JavaScript code requires a lot of practice and experience accumulation.

Let me give you a chestnut: Suppose we want to create a product display page.

 <code class="html">   <title>產(chǎn)品展示</title> <style> body { background-color: #f0f0f0; } .product { width: 300px; height: 200px; background-color: white; margin: 20px auto; box-shadow: 2px 2px 5px rgba(0,0,0,0.3); border-radius: 5px; overflow: hidden; } .product img { width: 100%; height: 100%; object-fit: cover; transition: transform 0.3s ease; } .product:hover img { transform: scale(1.1); } </style>   <div class="product"> <img src="/static/imghw/default1.png" data-src="product1.jpg" class="lazy" alt="How does the H5 page production reflect the effect"> </div>  </code>

This code is simple, but it already contains HTML structure, CSS styles and some simple JavaScript interaction effects (image hover enlargement). Of course, this is just a simple example. In actual projects, you need to use more and more complex code and techniques.

Performance optimization and best practices: This part is important and directly affects the user experience. Image compression, code optimization, caching strategies, etc. are all factors that need to be considered. I've seen many H5 pages, and the user experience was extremely poor due to performance issues, and the project ended up failing. So, don't ignore this aspect.

In short, the manifestation of the effect of H5 page is a systematic project that requires comprehensive consideration from multiple aspects such as design, code, and performance. There is no shortcut. Only by constantly learning and practicing can we make truly excellent works. Remember, user experience is the ultimate criterion of judgment.
