How to use the css margin property?
Definition and Usage
margin shorthand property sets all margin properties in a single declaration. This attribute can have 1 to 4 values.
Description
This shorthand property sets the width of all margins of an element, or sets the width of margins on each side.
The vertically adjacent margins of block-level elements will be merged, while inline elements will not actually occupy the top and bottom margins. The left and right margins of inline elements are not merged. Likewise, the margins of floated elements are not merged. It is allowed to specify negative margin values, but use caution when using them.
Note: Negative values are allowed.
Example 1
margin:10px 5px 15px 20px;
The top margin is 10px
The right margin is 5px
The bottom margin is 15px
The left margin is 20px
Example 2
margin:10px 5px 15px;
The top margin is 10px
The right and left margins are 5px
The bottom margin is 15px
Example 3
margin:10px 5px;
The top and bottom margins are 10px
Right margin and left margin is 5px
Example 4
margin:10px;
All 4 margins are 10px
Default value: 0
Inheritance: no
Version: CSS1
JavaScript Syntax:
object.style.margin="10px 5px"
Possible values
auto, calculated by the browser Margins.
length, specifies the margin value in specific units, such as pixels, centimeters, etc. The default value is 0px.
%, specifies margins based on a percentage of the width of the parent element.
inherit specifies that the margins should be inherited from the parent element.
Example
Set the 4 margins of the p element:
<html>
<head>
<style type="text/css">
p.margin {margin: 2cm 4cm 3cm 4cm}
</style>
</head>
<body>
<p>这个段落没有指定外边距。</p>
<p class="margin">这个段落带有指定的外边距。这个段落带有指定的外边距。这个段落带有指定的外边距。这个段落带有指定的外边距。这个段落带有指定的外边距。</p>
<p>这个段落没有指定外边距。</p>
</body>
</html>Effect output:
Browser support: All browsers support the margin attribute.
Note: The attribute value "inherit" is not supported by any version of Internet Explorer (including IE8).

React's Role in HTML: Enhancing User Experience
Apr 09, 2025 am 12:11 AM
React 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 and the Frontend: Building Interactive Experiences
Apr 11, 2025 am 12:02 AM
React 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 Components: Creating Reusable Elements in HTML
Apr 08, 2025 pm 05:53 PM
React 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's Ecosystem: Libraries, Tools, and Best Practices
Apr 18, 2025 am 12:23 AM
The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.
Frontend Development with React: Advantages and Techniques
Apr 17, 2025 am 12:25 AM
The 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. Backend Frameworks: A Comparison
Apr 13, 2025 am 12:06 AM
React 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.
React and the Frontend Stack: The Tools and Technologies
Apr 10, 2025 am 09:34 AM
React 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.
Understanding React's Primary Function: The Frontend Perspective
Apr 18, 2025 am 12:15 AM
React's main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.
