HTML5 is the new standard for HTML, XHTML and HTML DOM. HTML5 is the fifth version of HTML. Many elements have been deleted or modified in HTML5. HTML5 is designed to support multimedia on mobile devices, and HTML In comparison, the depth and breadth have been further improved.

The operating environment of this tutorial: Windows 10 system, HTML5 version, Dell G3 computer.
What is the relationship between html and html5
HTML stands for Hypertext Markup Language and is used to design web pages using markup language. HTML is a combination of hypertext, which defines the links between web pages, and markup language, which is used to define text documents within markup that define the structure of a web page. This language is used to annotate (in computer annotation) text so that a machine can understand it and manipulate the text accordingly.
Most markup (such as HTML) languages are human-readable. The language uses tags to define what operations must be performed on text. It is used to structure and render content on web pages.
HTML5 is the fifth version of HTML. Many elements have been deleted or modified in HTML5.
The difference between HTML5 and HTML
First of all, HTML5 has gone far beyond the scope of markup language. It is designed to support multimedia on mobile devices, and HTML In comparison, the depth and breadth have been further improved.
Next, let’s take a look at the declaration file types of the two:
HTML:

HTML5

As you can see from the above, in terms of document declaration, the declaration code of HTML is very long and complicated, while the declaration of HTML5 is simpler and easier to remember, so HTML5 is more beneficial to programmers than HTML. Read and develop quickly.
In addition, the structural semantics of the two are also different. HTML does not have structural semantic tags, which are usually named after
HTML5 has added a powerful drawing function. Through the drawing function and JS, animations and pictures can be realized. But HTML4.0 does not. In HTML5, Canvas and SVG can be used for drawing. Canvas is equivalent to a canvas and can draw 2D graphics through JavaScript. Canvas is rendered pixel by pixel. SVG is Scalable Vector Graphics, used to define vector-based graphics for the web. SVG strictly follows XML syntax. Its image files are readable and easy to modify and edit. They can be searched, indexed, scripted, or compressed. Can be printed with high quality at any resolution.
In addition to the above points, the powerful HTML5 also adds a new video tag. This function is not available in HTML4.0. Inserting a video using HTML4.0 requires a long section of code, but using HTML5 only requires the video tag.
I am a front-end engineer who has been engaged for five years. I have compiled the most comprehensive front-end learning materials. From the most basic HTML CSS JS to HTML5 practical project learning materials, I have compiled them for everyone. I am a front-end friend. If you want to learn web front-end, or are changing careers, or are college students, or want to improve your abilities at work, if you are learning, you can message me privately if you need. This is my front-end development qun , [603] [985] [993], if you have any questions about learning web front-end (learning methods, learning efficiency, how to get a job), you can ask me, and finally you can click to follow!
Summary:
1. Document declaration difference
2. Structural semantic difference
html: There are no tags that reflect structural semantics, such as:
html5: Added many semantic tags, such as:

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.
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.
