The HTML5 details tag creates an expandable detail section where the user can click on the title to show or hide additional information. This applies to displaying non-essential or auxiliary content, such as long articles or technical details. The main features include: 1. Clickable title; 2. Expandable content; 3. Interactive behavior (click the title to expand/hide). The tag is widely supported by modern browsers such as Chrome, Firefox, Safari, and Edge.

Basics of HTML5 details tags

The HTML5 details tag is used to create an expandable detail section, allowing users to click to view or hide additional information. This is very useful for displaying non-essential or auxiliary content, such as long articles or technical details.

grammar

 <code class="html"><details> <summary>可点击的标题</summary> <p>可展开的内容</p> </details></code>

property

open: Boolean value, indicating whether the details are expanded by default.
onToggle: The event handler that fires when the details are expanded or hidden.

characteristic

Clickable title: With its summary element, clickable titles can be created to expand or hide details.
Expandable content: Any HTML element can be placed inside the details element to display when expanded. Content usually appears in paragraphs, lists, or other formats.
Interactive behavior: Clicking on the title expands or hides details. If the open property is set to true, the details are expanded by default.

usage

HTML5 details tags are usually used in the following situations:

Show additional information such as technical documentation or FAQs.
Create foldable sections, such as navigation menus or sidebars.
Provide interactive content, such as interactive tutorials or quizzes.

Browser support

The details tag is widely supported by all modern browsers, including Chrome, Firefox, Safari, and Edge.

Example

Here is an example to create a default expanded details section:

 <code class="html"><details open> <summary>动物王国</summary> <p>动物王国充满着各种各样的生物，从微小的昆虫到庞大的鲸鱼。</p> </details></code>

From XML to C : Data Transformation and ManipulationApr 16, 2025 am 12:08 AM

Converting from XML to C and performing data operations can be achieved through the following steps: 1) parsing XML files using tinyxml2 library, 2) mapping data into C's data structure, 3) using C standard library such as std::vector for data operations. Through these steps, data converted from XML can be processed and manipulated efficiently.

C# vs. C : Memory Management and Garbage CollectionApr 15, 2025 am 12:16 AM

C# uses automatic garbage collection mechanism, while C uses manual memory management. 1. C#'s garbage collector automatically manages memory to reduce the risk of memory leakage, but may lead to performance degradation. 2.C provides flexible memory control, suitable for applications that require fine management, but should be handled with caution to avoid memory leakage.

Beyond the Hype: Assessing the Relevance of C TodayApr 14, 2025 am 12:01 AM

C still has important relevance in modern programming. 1) High performance and direct hardware operation capabilities make it the first choice in the fields of game development, embedded systems and high-performance computing. 2) Rich programming paradigms and modern features such as smart pointers and template programming enhance its flexibility and efficiency. Although the learning curve is steep, its powerful capabilities make it still important in today's programming ecosystem.

The C Community: Resources, Support, and DevelopmentApr 13, 2025 am 12:01 AM

C Learners and developers can get resources and support from StackOverflow, Reddit's r/cpp community, Coursera and edX courses, open source projects on GitHub, professional consulting services, and CppCon. 1. StackOverflow provides answers to technical questions; 2. Reddit's r/cpp community shares the latest news; 3. Coursera and edX provide formal C courses; 4. Open source projects on GitHub such as LLVM and Boost improve skills; 5. Professional consulting services such as JetBrains and Perforce provide technical support; 6. CppCon and other conferences help careers

C# vs. C : Where Each Language ExcelsApr 12, 2025 am 12:08 AM

C# is suitable for projects that require high development efficiency and cross-platform support, while C is suitable for applications that require high performance and underlying control. 1) C# simplifies development, provides garbage collection and rich class libraries, suitable for enterprise-level applications. 2)C allows direct memory operation, suitable for game development and high-performance computing.

The Continued Use of C : Reasons for Its EnduranceApr 11, 2025 am 12:02 AM

C Reasons for continuous use include its high performance, wide application and evolving characteristics. 1) High-efficiency performance: C performs excellently in system programming and high-performance computing by directly manipulating memory and hardware. 2) Widely used: shine in the fields of game development, embedded systems, etc. 3) Continuous evolution: Since its release in 1983, C has continued to add new features to maintain its competitiveness.

The Future of C and XML: Emerging Trends and TechnologiesApr 10, 2025 am 09:28 AM

The future development trends of C and XML are: 1) C will introduce new features such as modules, concepts and coroutines through the C 20 and C 23 standards to improve programming efficiency and security; 2) XML will continue to occupy an important position in data exchange and configuration files, but will face the challenges of JSON and YAML, and will develop in a more concise and easy-to-parse direction, such as the improvements of XMLSchema1.1 and XPath3.1.

Modern C Design Patterns: Building Scalable and Maintainable SoftwareApr 09, 2025 am 12:06 AM

The modern C design model uses new features of C 11 and beyond to help build more flexible and efficient software. 1) Use lambda expressions and std::function to simplify observer pattern. 2) Optimize performance through mobile semantics and perfect forwarding. 3) Intelligent pointers ensure type safety and resource management.
