What to learn when making H5 pages

H5 page production is a comprehensive skill covering the use of HTML, CSS, JavaScript and server-side technologies. HTML is responsible for building page frameworks, CSS determines page styles, JavaScript makes page dynamic, and other knowledge includes image optimization, API usage and server interaction technology.

H5 page production, do you think it’s as simple as stacking some labels? Naive! The threshold for this thing seems low, and it takes a lot of effort to play with it. In this article, let’s take a look at the twists and turns behind it, so that you can avoid detours. After reading it, you can not only make a decent page, but also understand why the pages made by others look so pleasant, and your... well, it's hard to describe it.

First of all, it must be clear that H5 page production is not a single skill, but a complex. You have to understand some HTML, CSS, JavaScript, and even some server-side technologies, depending on how complex the page you want to make is.

HTML, this thing is the skeleton of a web page. You have to know how to use tags to build the structure of the page, such as <div> , <code><span></span> , and <img src="/static/imghwm/default1.png" data-src="image.jpg" class="lazy" alt="What to learn when making H5 pages" > , how to nest and layout, these are the foundations in the basics. It is not enough to just use tags. You also have to understand semantics to make your code clearer, more conducive to search engine optimization, and more conducive to team collaboration. Don’t underestimate these basics. Many beginners just get stuck here. The code is written in a mess and it’s more difficult to modify than rewrite.

CSS, this is the skin of the web page, determines the style of the page. You need to master the concepts of selectors, box models, layouts, responsive designs, and more. Responsive design is especially important. Nowadays, various devices have a variety of screen sizes. Your page must be able to adapt to various screen sizes, otherwise the user experience will be extremely poor. In this regard, Flexbox and Grid layouts are your good helpers and you must master them proficiently. Don't forget that CSS preprocessors, such as Sass or Less, can greatly improve your development efficiency and make you more elegant in writing CSS.

JavaScript, this is the soul of a web page, making the page move. You need to master the basic syntax of JavaScript, DOM operations, event processing, AJAX, etc. Now many H5 pages use various JavaScript frameworks, such as React, Vue, and Angular. Learning these frameworks can help you achieve twice the result with half the effort, but don’t expect quick results, it takes time and practice. Remember, when writing JavaScript, you should pay attention to the quality of your code. Don’t write a bunch of stinky and long code. It will drive you crazy if you maintain it later.

In addition to these front-end technologies, you need to know some other knowledge. For example, you need to understand the optimization of images, how to use the appropriate image format, and how to compress the image size to improve the page loading speed. You also need to learn some commonly used H5 APIs, such as geolocation API, camera API, etc. These APIs can allow you to create cooler page effects. If your page needs to interact with the server, you also need to learn some server-side technologies, such as Node.js or PHP.

Next, let's take a look at some code examples and experience the charm of H5:

A simple HTML structure:

 <code class="html">   <title>My H5 Page</title> <link rel="stylesheet" href="style.css">   <div class="container"> <h1 id="Hello-H">Hello, H5!</h1> <img src="/static/imghwm/default1.png" data-src="image.jpg" class="lazy" alt="My Image"> </div> <script src="script.js"></script>  </code>

Corresponding CSS style:

 <code class="css">.container { display: flex; justify-content: center; align-items: center; height: 100vh; } h1 { font-size: 3em; color: #333; } img { width: 200px; height: auto; }</code>

Finally, remember that practice brings true knowledge. Only by doing more projects, reading more excellent works, and thinking more can you truly master the essence of H5 page production. Don’t be afraid of making mistakes. Start with a simple page and gradually increase the difficulty. You will find that the world of H5 is much more exciting than you think. I wish you a good H5 developer!
