HTML (Hypertext Markup Language) is a markup language used to build web pages. It is the basis for building web pages. In this article, we'll cover how to write HTML and add style and functionality to your website.
- Writing HTML documents
HTML documents are composed of tags, and tags can be nested. Each tag has an opening tag and a closing tag, for example:
<html>
<head>
<title>这是网页标题</title>
</head>
<body>
<h1 id="欢迎来到我的网站">欢迎来到我的网站</h1>
<p>这是一个段落</p>
</body>
</html>In this example, we have a root tag of HTML, a
tag that contains the title of the web page, and a tag, we have antag for the heading and a
tag for the paragraph.
- Tags and attributes
HTML tags can have attributes to specify the characteristics of the tag. For example, the 
tag can specify the URL of the image through the src attribute, as shown below:
<img src="/static/imghwm/default1.png" data-src="https://example.com/image.jpg" class="lazy" alt="这是图像的描述">
In this example, we specify the URL of the image using the src attribute, and the alt attribute provides a description of the image.
- Links
In a web page, we can add links to other web pages or local files. Use the tag to create a link, for example:
<a href="https://example.com/">这是一个链接</a>
In this example, we use the href attribute to specify the URL of the link target.
- List
We can use lists to organize information. HTML has two types of lists: ordered lists and unordered lists. Ordered lists use the
- tag, while unordered lists use the
- tag. For example:
<ol>
<li>第一项</li>
<li>第二项</li>
<li>第三项</li>
</ol>
<ul>
<li>第一项</li>
<li>第二项</li>
<li>第三项</li>
</ul>In this example, we use the
- tag to create an ordered list, and the
- tag to create an unordered list.
- Style
We can use CSS (Cascading Style Sheets) to add styles to the website. CSS is a style sheet language used to describe the appearance and layout of web pages. For example:
<!DOCTYPE html>
<html>
<head>
<title>这是网页标题</title>
<style>
h1 {
color: red;
font-size: 48px;
}
p {
font-size: 24px;
line-height: 1.5;
}
</style>
</head>
<body>
<h1 id="欢迎来到我的网站">欢迎来到我的网站</h1>
<p>这是一个段落</p>
</body>
</html>In this example, we embed the
- JavaScript
We can use JavaScript to add interactive and dynamic features to our website. JavaScript is a scripting language that can be used with HTML and CSS. For example:
<!DOCTYPE html>
<html>
<head>
<title>这是网页标题</title>
</head>
<body>
<h1 id="欢迎来到我的网站">欢迎来到我的网站</h1>
<button onclick="alert('你点击了按钮')">点击我</button>
</body>
</html>In this example, we create a button using the
Summary
In this article, we introduced the basics of HTML, including writing HTML documents, tags and attributes, links, lists, styles, and JavaScript. With these basics, you can start building simple websites and applications. However, keep in mind that if you want to build a high-quality and maintainable website, you need to learn these basics in depth and move on to advanced topics like object-oriented programming, frameworks, and libraries.

React's Performance Bottlenecks: Identifying and Optimizing Slow ComponentsApr 26, 2025 am 12:25 AMReact performance bottlenecks are mainly caused by inefficient rendering, unnecessary re-rendering and calculation of component internal heavy weight. 1) Use ReactDevTools to locate slow components and apply React.memo optimization. 2) Optimize useEffect to ensure that it only runs when necessary. 3) Use useMemo and useCallback for memory processing. 4) Split the large component into small components. 5) For big data lists, use virtual scrolling technology to optimize rendering. Through these methods, the performance of React applications can be significantly improved.
Alternatives to React: Exploring Other JavaScript UI Libraries and FrameworksApr 26, 2025 am 12:24 AMSomeone might look for alternatives to React because of performance issues, learning curves, or exploring different UI development methods. 1) Vue.js is praised for its ease of integration and mild learning curve, suitable for small and large applications. 2) Angular is developed by Google and is suitable for large applications, with a powerful type system and dependency injection. 3) Svelte provides excellent performance and simplicity by compiling it into efficient JavaScript at build time, but its ecosystem is still growing. When choosing alternatives, they should be determined based on project needs, team experience and project size.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
