HTML provides 3 list modes: 1. Ordered list, created using "
" and "
- " tags, the contents between the ordered lists are in order; 2. Create an unordered list using the "
" and "
- " tags; 3. Define the list using the "
", "
- " and "
- " tags create.
The operating environment of this tutorial: Windows 7 system, HTML5 version, Dell G3 computer.
HTML list (List) can organize several related pieces of content to make the content look more organized. Within lists you can place text, images, links, etc. You can also define a list within another list (nested lists).
HTML provides us with three different forms of lists:
- Ordered list, use
- tag
- Unordered list , use
- tag
- to define the list, use
- tag
1. Ordered list
In HTML, the
- tag is used to represent an ordered list. The content in an ordered list has a sequence, such as a series of steps in a recipe. These steps need to be completed in order. In this case, an ordered list can be used.
- tags:
- is the abbreviation of order list, which means an ordered list. It can number each item in the list, starting from the number 1 by default.
- is the abbreviation of list item, which represents each item in the list. The number of
- in
- indicates how many pieces of content there are. List items can contain text, images, links, etc., or even another list.
Note that
- is generally used in conjunction with
- and will not appear alone, and it is not recommended to use other tags other than
- directly in
- .
2. Unordered list
HTML uses the
- tag to represent an unordered list. Unordered lists are similar to ordered lists, both use the
- tag to represent each item in the list, but the contents in the unordered list are not in order. For example, the types of breakfast do not need to indicate the order, then an unordered list can be used.
Let’s look at a simple example:<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>HTML无序列表</title> </head> <body> <p>早餐的种类：</p> <ul> <li>鸡蛋</li> <li>牛奶</li> <li>面包</li> <li>生菜</li> </ul> </body> </html><!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>HTML无序列表</title> </head> <body> <p>早餐的种类：</p> <ul> <li>鸡蛋</li> <li>牛奶</li> <li>面包</li> <li>生菜</li> </ul> </body> </html>浏览器运行结果如图所示：
无序列表需要使用
- 和
- 标签：
- 是 unordered list 的简称，表示无序列表。
-
- 和
- 中的
- 一样，都表示列表中的每一项。默认情况下，无序列表的每一项都使用
●符号表示。
- 一样，都表示列表中的每一项。默认情况下，无序列表的每一项都使用
注意，
- 一般和
- 配合使用，不会单独出现，而且不建议在
- 中直接使用除
- 之外的其他标签。
3. 定义列表
在 HTML 中，
- 标签用于创建定义列表。定义列表由标题（术语）和描述两部分组成，描述是对标题的解释和说明，标题是对描述的总结和提炼。
- 和
- 标签：
- 是 definition list 的简称，表示定义列表。
- 是 definition term 的简称，表示定义术语，也就是我们说的标题。
- 是 definition description 的简称，表示定义描述 。
可以认为
- 定义了一个概念（术语），
- 用来对概念（术语）进行解释。
注意，
- 和
- 是同级标签，它们都是
- 的子标签。一般情况下，每个
- 搭配一个
- ，一个
- 可以包含多对
- 和
- 。
我们来看一个简单的例子：<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>HTML定义列表</title> </head> <body> <dl> <dt>HTML</dt> <dd>HTML 是一种专门用来开发网页的标记语言，您可以转到《<a href="http://www.php.cn/course/list/11.html" target="_blank">HTML教程</a>》了解更多。</dd> <dt>CSS</dt> <dd>CSS 层叠样式表可以控制 HTML 文档的显示样式，用来美化网页，您可以转到《<a href="https://www.php.cn/course/list/12.html" target="_blank">CSS教程</a>》了解更多。</dd> <dt>JavaScript</dt> <dd>JavaScript 简称 JS，是一种用来开发网站（包括前端和后台）的脚本编程语言，您可以转到《<a href="https://www.php.cn/course/list/2.html" target="_blank">JS教程</a>》了解更多。</dd> </dl> </body> </html> - 和
- 虽然是同级标签，但是它们的默认样式不同，
- 带有一段缩进，而
- 顶格显示，这样层次更加分明。
4. 总结
列表分类 说明 有序列表 - 表示有序列表，
- 表示列表中的每一项，默认使用阿拉伯数字编号。
无序列表 - 表示无序列表，
- 表示列表中的每一项，默认使用
●符号作为作为每一项的标记。
定义列表 - 表示定义列表，
- 表示定义术语、
- 表示定义描述。一般情况下，每个
- 搭配一个
- ，一个
- 可以包含多对
- 和
- 。

定义列表具体语法格式如下：<dl> <dt>标题1<dt> <dd>描述文本2<dd> <dt>标题2<dt> <dd>描述文本2<dd> <dt>标题3<dt> <dd>描述文本3<dd> </dl>定义列表需要使用
- 、
- 之外的其他标签。
- 标签：
- tag to represent each item in the list, but the contents in the unordered list are not in order. For example, the types of breakfast do not need to indicate the order, then an unordered list can be used.
Let’s look at a simple example:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>HTML有序列表</title> </head> <body> <p>煮米饭的步骤：</p> <ol> <li>将水煮沸</li> <li>加入一勺米</li> <li>搅拌均匀</li> <li>继续煮10分钟</li> </ol> </body> </html>Ordered lists require the use of
- and

Frontend Development with React: Advantages and TechniquesApr 17, 2025 am 12:25 AMThe advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.
React vs. Other Frameworks: Comparing and Contrasting OptionsApr 17, 2025 am 12:23 AMReact is a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.
Demystifying React in HTML: How It All WorksApr 17, 2025 am 12:21 AMReact operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.
React in Action: Examples of Real-World ApplicationsApr 17, 2025 am 12:20 AMReact is widely used in e-commerce, social media and data visualization. 1) E-commerce platforms use React to build shopping cart components, use useState to manage state, onClick to process events, and map function to render lists. 2) Social media applications interact with the API through useEffect to display dynamic content. 3) Data visualization uses react-chartjs-2 library to render charts, and component design is easy to embed applications.
Frontend Architecture with React: Best PracticesApr 17, 2025 am 12:10 AMBest practices for React front-end architecture include: 1. Component design and reuse: design a single responsibility, easy to understand and test components to achieve high reuse. 2. State management: Use useState, useReducer, ContextAPI or Redux/MobX to manage state to avoid excessive complexity. 3. Performance optimization: Optimize performance through React.memo, useCallback, useMemo and other methods to find the balance point. 4. Code organization and modularity: Organize code according to functional modules to improve manageability and maintainability. 5. Testing and Quality Assurance: Testing with Jest and ReactTestingLibrary to ensure the quality and reliability of the code
React Inside HTML: Integrating JavaScript for Dynamic Web PagesApr 16, 2025 am 12:06 AMTo integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.
The Benefits of React: Performance, Reusability, and MoreApr 15, 2025 am 12:05 AMReact’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.
React: Creating Dynamic and Interactive User InterfacesApr 14, 2025 am 12:08 AMReact is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.
