Web Front-endFront-end Q&AHow to set the mouse to zoom in and disappear after passing through the rounded corners in css3How to set the mouse to zoom in and disappear after passing through the rounded corners in css3
Method: 1. Use the ":hover" selector to set the style when the mouse passes over the element. The syntax is "element:hover{style code}"; 2. Use "element {" in the style code when the mouse passes over it. animation: name time}" statement to bind animation to the element; 3. Use the "@keyframes fadenum{100%{border-radius:0;}}" statement to set the effect of enlarging the rounded corners until they disappear.

How to set the mouse to disappear after enlarging the rounded corner in css3
1. :hover pseudo-class selector setting style
In css:hover is a Pseudo-class selector, :hover pseudo-class selector adds a special style to this element when the mouse is moved over the element. The :hover selector applies to all elements.
:Hover is a special style added when the mouse moves over the link.
In IE, "" must be declared to ensure that the ":hover" selector can be effective
2. Use animation to bind animation
Theanimation property is a shorthand property for setting six animation properties:
animation-name
animation-duration
animation-timing-function
animation-delay
-
animation-iteration-count
animation-direction
3. Use @keyframes to set animations
Through @keyframes rules , you can create animations.
The principle of creating animation is to gradually change one set of CSS styles into another set of styles.
You can change this set of CSS styles multiple times during the animation process.
Specify the time when the change occurs as a percentage, or through the keywords "from" and "to", which are equivalent to 0% and 100%.
0% is the start time of the animation, 100% is the end time of the animation.
For best browser support, you should always define 0% and 100% selectors.
Examples are as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>123</title>
<style>
div
{
width: 80px;
height: 50px;
background:pink;
border:1px solid #000;
border-radius:50%;
}
div:hover
{
animation:fadenum 5s;
}
@keyframes fadenum{
100%{border-radius:0;}
}
}
</style>
</head>
<body>
<div></div>
</body>
</html>Output results:

React: The Foundation for Modern Frontend DevelopmentApr 19, 2025 am 12:23 AMReact is a JavaScript library for building modern front-end applications. 1. It uses componentized and virtual DOM to optimize performance. 2. Components use JSX to define, state and attributes to manage data. 3. Hooks simplify life cycle management. 4. Use ContextAPI to manage global status. 5. Common errors require debugging status updates and life cycles. 6. Optimization techniques include Memoization, code splitting and virtual scrolling.
The Future of React: Trends and Innovations in Web DevelopmentApr 19, 2025 am 12:22 AMReact's future will focus on the ultimate in component development, performance optimization and deep integration with other technology stacks. 1) React will further simplify the creation and management of components and promote the ultimate in component development. 2) Performance optimization will become the focus, especially in large applications. 3) React will be deeply integrated with technologies such as GraphQL and TypeScript to improve the development experience.
React: A Powerful Tool for Building UI ComponentsApr 19, 2025 am 12:22 AMReact is a JavaScript library for building user interfaces. Its core idea is to build UI through componentization. 1. Components are the basic unit of React, encapsulating UI logic and styles. 2. Virtual DOM and state management are the key to component work, and state is updated through setState. 3. The life cycle includes three stages: mount, update and uninstall. The performance can be optimized using reasonably. 4. Use useState and ContextAPI to manage state, improve component reusability and global state management. 5. Common errors include improper status updates and performance issues, which can be debugged through ReactDevTools. 6. Performance optimization suggestions include using memo, avoiding unnecessary re-rendering, and using us
Using React with HTML: Rendering Components and DataApr 19, 2025 am 12:19 AMUsing HTML to render components and data in React can be achieved through the following steps: Using JSX syntax: React uses JSX syntax to embed HTML structures into JavaScript code, and operates the DOM after compilation. Components are combined with HTML: React components pass data through props and dynamically generate HTML content, such as. Data flow management: React's data flow is one-way, passed from the parent component to the child component, ensuring that the data flow is controllable, such as App components passing name to Greeting. Basic usage example: Use map function to render a list, you need to add a key attribute, such as rendering a fruit list. Advanced usage example: Use the useState hook to manage state and implement dynamics
React's Purpose: Building Single-Page Applications (SPAs)Apr 19, 2025 am 12:06 AMReact is the preferred tool for building single-page applications (SPAs) because it provides efficient and flexible ways to build user interfaces. 1) Component development: Split complex UI into independent and reusable parts to improve maintainability and reusability. 2) Virtual DOM: Optimize rendering performance by comparing the differences between virtual DOM and actual DOM. 3) State management: manage data flow through state and attributes to ensure data consistency and predictability.
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

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),
