The audio formats supported by html5 are: 1. MP3 format, which is designed to greatly reduce the amount of audio data; 2. Ogg format, which is a completely free, open and patent-free audio format Compression format; 3. Wav format is a sound file format developed by Microsoft.
The operating environment of this tutorial: Windows 7 system, HTML5 version, Dell G3 computer.
HTML5 provides a standard for playing audio files. You can use the
The embedded audio formats mainly include ogg, mp3, wav, etc.
| Format | MIME-type |
|---|---|
| audio/mpeg | |
| audio/ogg | |
| audio/wav |
- ogg: When the ogg file only encapsulates audio encoding, it will become an audio file. The ogg audio file extension is ogg. The ogg audio format is similar to the mp3 audio format. The difference is that the ogg format is completely free and has no patent restrictions. Under the same conditions, the sound quality and size of ogg format audio files are better than those of mp3 audio format.
- mp3: The current mainstream audio format, its audio file extension is mp3. Like the mpeg4 video format, the mp3 audio format also has many restrictions such as patents and copyrights. However, because of the support of major hardware providers, mp3 still maintains a high usage rate relying on its rich resources and good compatibility. MP3 is an audio compression technology, its full name is Moving Picture Experts Group Audio Layer III (Moving Picture Experts Group Audio Layer III), referred to as MP3. It is designed to significantly reduce the amount of audio data. Using MPEG Audio Layer 3 technology, music is compressed into smaller files with a compression rate of 1:10 or even 1:12. For most users, the playback sound quality is no better than the original uncompressed audio. A significant decline.
- wav: A sound file format developed by Microsoft (Microsoft), its extension is wav. As a lossless compressed audio format, WAV's sound quality is the best among the three audio format files, but its size is also the largest. The biggest advantage of the wav audio format is that it is widely supported by the Windows platform and its applications and is a standard Windows file.

React vs. Backend Frameworks: A ComparisonApr 13, 2025 am 12:06 AMReact is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
HTML and React: The Relationship Between Markup and ComponentsApr 12, 2025 am 12:03 AMThe relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.
React and the Frontend: Building Interactive ExperiencesApr 11, 2025 am 12:02 AMReact is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent
React and the Frontend Stack: The Tools and TechnologiesApr 10, 2025 am 09:34 AMReact is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.
React's Role in HTML: Enhancing User ExperienceApr 09, 2025 am 12:11 AMReact combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
React Components: Creating Reusable Elements in HTMLApr 08, 2025 pm 05:53 PMReact components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.
React Strict Mode PurposeApr 02, 2025 pm 05:51 PMReact Strict Mode is a development tool that highlights potential issues in React applications by activating additional checks and warnings. It helps identify legacy code, unsafe lifecycles, and side effects, encouraging modern React practices.
React Fragments UsageApr 02, 2025 pm 05:50 PMReact Fragments allow grouping children without extra DOM nodes, enhancing structure, performance, and accessibility. They support keys for efficient list rendering.

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),
