H5 page development involves the use of HTML, CSS and JavaScript technologies to create web page structure, style and interactive functions. It requires understanding concepts such as semantic tags, box models, DOM operations and event listening. Create dynamic web pages by writing HTML code, using CSS to control styles, and using JavaScript to process user interaction.
H5 page, what's happening
You ask how to make the H5 page? This question is like asking “How to write a novel”, and the scope is too wide! However, I can make you a clearer understanding of H5 development and even a simple page.
In this article, let’s not talk about those boring theories, let’s talk about actual operations and pitfalls. After reading it, you will understand the ins and outs of H5 page development and some tips that can help you avoid detours.
Let’s talk about the basics first. H5, also known as HTML5, is a markup language itself, responsible for the page structure. But having a structure alone is not enough. You have to use CSS to dress it up and make it beautiful, which is the style. Finally, JavaScript gives it the soul, let it move, and achieve various interactive effects. All these three musketeers are indispensable.
You may ask, how to use these three things? To put it bluntly, it is just writing code. HTML uses tags to build a framework, CSS uses selectors and attributes to control styles, and JavaScript uses functions and events to handle user interactions. This is not a simple "Hello World!", you need to understand semantic tags, box models, DOM operations, event listening, etc.
For example, you want to do a simple picture carousel. HTML is responsible for creating picture containers and picture elements, CSS is responsible for setting the picture size, position and transition effects, and JavaScript is responsible for controlling the switching and animation of pictures.
The code looks like this, don't be scared, it's actually very simple:
<code class="html"> <title>圖片輪播</title> <style> .slider { width: 300px; height: 200px; overflow: hidden; } .slider img { width: 300px; height: 200px; transition: opacity 0.5s ease-in-out; } .slider img.active { opacity: 1; } .slider img:not(.active) { opacity: 0; } </style> <div class="slider"> <img class="active lazy" src="/static/imghw/default1.png" data-src="image1.jpg" alt="Image 1"> <img src="/static/imghw/default1.png" data-src="image2.jpg" class="lazy" alt="Image 2"> <img src="/static/imghw/default1.png" data-src="image3.jpg" class="lazy" alt="Image 3"> </div> <script> const images = document.querySelectorAll('.slider img'); let current = 0; setInterval(() => { images[current].classList.remove('active'); current = (current 1) % images.length; images[current].classList.add('active'); }, 3000); // 每3秒切換一次</script> </code>
This code is simple, but it contains a combination of HTML, CSS and JavaScript. Note that the image path needs to be replaced with your own image.
Of course, this is just the most basic carousel. In actual applications, you may need to consider more complex scenarios, such as touch sliding, indicator points, automatic playback control, etc. All of these require more granular JavaScript code to implement.
Speaking of this, you may encounter various problems, such as browser compatibility, performance optimization, code debugging, etc. For browser compatibility issues, you have to consider the degree of support for CSS and JavaScript by different browsers; for performance optimization, you need to learn some optimization techniques, such as reducing HTTP requests, using caches, etc.; for code debugging, you need to master some debugging tools, such as browser developer tools.
Remember, H5 development is not achieved overnight and requires continuous learning and practice. Only by reading more documents, writing more code, and debugging more can you become a true H5 master. Don't be afraid to make mistakes. Start with simple examples and accumulate experience step by step, and you can make the H5 page you want. It’s like building a house. First laying the foundation, then building up one layer after another, and finally building a high-rise building. come on!

Describe different CSS units and when to use them
Jul 27, 2025 am 04:24 AM
In web development, the choice of CSS units depends on design requirements and responsive performance. 1. Pixels (px) are used to fix sizes such as borders and icons, but are not conducive to responsive design; 2. Percentage (%) is adjusted according to the parent container, suitable for streaming layout but attention to context dependence; 3.em is based on the current font size, rem is based on the root element font, suitable for elastic fonts and unified theme control; 4. Viewport units (vw/vh/vmin/vmax) are adjusted according to the screen size, suitable for full-screen elements and dynamic UI; 5. Auto, inherit, initial and other values are used to automatically calculate, inherit or reset styles, which helps to flexibly layout and style management. The rational use of these units can improve page flexibility and responsiveness.

Supports multiple filter functions such as blur, brightness, contrast, etc. and can be superimposed; 3. It is often used in glass card design, and it is necessary to ensure that the elements overlap with the background; 4.

This attribute only takes effect when there is content behind the elements.
How to style links in CSS?
Jul 29, 2025 am 04:25 AM
The style of the link should distinguish different states through pseudo-classes. 1. Use a:link to set the unreached link style, 2. a:visited to set the accessed link, 3. a:hover to set the hover effect, 4. a:active to set the click-time style, 5. a:focus ensures keyboard accessibility, always follow the LVHA order to avoid style conflicts. You can improve usability and accessibility by adding padding, cursor:pointer and retaining or customizing focus outlines.

How to center text in CSS?
Jul 27, 2025 am 03:16 AM
Use text-align:center to achieve horizontal centering of text; 2. Use Flexbox's align-items:center and justify-content:center to achieve vertical and horizontal centering; 3. Single-line text can be vertically centered by setting line-height equal to the container height; 4. Absolute positioning elements can be combined with top: 50%, left: 50% and transform:translate (-50%, -50%) to achieve centering; 5. CSSGrid's place-items:center can also achieve dual-axis centering at the same time. It is recommended to use Flexbox or Grid first in modern layouts.
What are user agent stylesheets?
Jul 31, 2025 am 10:35 AM
User agent stylesheets are the default CSS styles that browsers automatically apply to ensure that HTML elements that have not added custom styles are still basic readable. They affect the initial appearance of the page, but there are differences between browsers, which may lead to inconsistent display. Developers often solve this problem by resetting or standardizing styles. Use the Developer Tools' Compute or Style panel to view the default styles. Common coverage operations include clearing inner and outer margins, modifying link underscores, adjusting title sizes and unifying button styles. Understanding user agent styles can help improve cross-browser consistency and enable precise layout control.
