You can use the "text-overflow" attribute in CSS to prohibit content overflow. This attribute specifies what happens when the text overflows the containing element. The syntax is "text-overflow: clip | ellipsis | ellipsis-word ".

How to prevent content overflow in css?
Use text-overflow attribute to achieve.
The text-overflow property specifies what happens when text overflows the containing element.
1. Text-overflow syntax:
text-overflow : clip | ellipsis | ellipsis-word
text-overflow parameter value and explanation:
clip : 不显示省略标记（...），而是简单的裁切 ellipsis : 当对象内文本溢出时显示省略标记（...） ellipsis-word : 当对象内文本溢出时显示省略标记（...）(word) white-space:nowrap;/*禁止换行,为text-overflow作准备*/ overflow:hidden; /*禁止文本溢出显示,为text-overflow作准备*/
text-ellipsis is a special style. The relevant explanation is as follows: The text-overflow attribute is just an annotation, whether to display an omission mark when the text overflows. There are no other style attribute definitions. To achieve the effect of generating ellipses when overflowing, you must also define: forcing text to be displayed in one line (white-space:nowrap) and overflowing content to be hidden (overflow:hidden). Only in this way can the effect of displaying ellipses in overflowing text be achieved.
The simple understanding is that I want to limit the text to one line (white-space: nowrap;), make sure this line is limited (width), and your overflow part needs to be hidden (overflow: hidden;) ), and then an ellipsis (text-overflow: ellipsis) appears

2. Usage of white-space
white The -space attribute declares how to handle whitespace characters in elements during the layout process. (The white space character here should refer to the space or carriage return we type on the keyboard, because no matter what white-space is set with or
, there will be a space or carriage return.)
The following is the white space on wschool -space possible values:
normal Default. White space is ignored by the browser.
pre White space will be preserved by the browser. It behaves like the
tag in HTML. <p>nowrap The text will not wrap. The text will continue on the same line until the <br> tag is encountered. </p><p>pre-wrap Preserves whitespace sequences, but wraps normally. </p><p>pre-line merges whitespace sequences but retains newlines. </p><p>inherit specifies that the value of the white-space attribute should be inherited from the parent element. </p><pre class='brush:php;toolbar:false;'><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

React: The Power of a JavaScript Library for Web DevelopmentApr 18, 2025 am 12:25 AMReact is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and
React's Ecosystem: Libraries, Tools, and Best PracticesApr 18, 2025 am 12:23 AMThe 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.
React and Frontend Development: A Comprehensive OverviewApr 18, 2025 am 12:23 AMReact is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability
The Power of React in HTML: Modern Web DevelopmentApr 18, 2025 am 12:22 AMThe application of React in HTML improves the efficiency and flexibility of web development through componentization and virtual DOM. 1) React componentization idea breaks down the UI into reusable units to simplify management. 2) Virtual DOM optimization performance, minimize DOM operations through diffing algorithm. 3) JSX syntax allows writing HTML in JavaScript to improve development efficiency. 4) Use the useState hook to manage state and realize dynamic content updates. 5) Optimization strategies include using React.memo and useCallback to reduce unnecessary rendering.
Understanding React's Primary Function: The Frontend PerspectiveApr 18, 2025 am 12:15 AMReact'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.
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.
