With the rapid development of the Internet, web pages have become indispensable in our daily lives part. As more and more people begin to use various devices to access web pages, it becomes particularly important to ensure the accessibility and maintainability of web pages. This article will introduce how to apply web standards to improve the accessibility and maintainability of web pages, and give specific code examples.
1. Improvement of accessibility
tags to represent paragraphs, etc.
Sample code:
<h1>这是一个标题</h1> <p>这是一个段落。</p>
Sample code:
<img src="image.jpg" alt="这是一张图片的描述性文本">

// utils.js export function formatDate(date) { return new Date(date).toLocaleDateString('en-US'); }
By applying the above web standards, we can improve the accessibility and maintainability of web pages. Both from the user's perspective and from the developer's perspective, it can provide better experience and efficiency. I hope that the code examples provided in this article can bring you some inspiration to apply Web standards to actual development.
