CSS is a language for designing web pages that allows us to control the layout, style and interaction of the page. "Unselectable" (user-select:none) is an attribute provided by CSS, which can be used to prevent users from selecting text content on the page. In many cases, this property is very useful, but in some cases it can be a source of trouble.
Let’s first look at the advantages of the “unselectable” attribute. In some web applications, we may need to display sensitive information on the page, such as passwords or account information, etc. This information is not expected to be copied or viewed by users. In this case, we can use the "unselectable" attribute to prevent users from selecting and copying this information and protect the security of this information. In addition, the "unselectable" attribute can be used to prevent plagiarism, protect the website's intellectual property, and give copyright owners greater control over how their website's content is used.
However, the use of the "unselectable" attribute also has some disadvantages, and it sometimes ruins the user experience. On a website where users often interact, such as an online magazine or news website, users may need to extract or store fragments of articles of interest. At this time, the "unselectable" attribute will be like a high wall, preventing users from extracting their own information. Needed content, this will obviously make the user experience very bad. In addition, in more extreme cases, the "unselectable" attribute may even prevent users from performing some necessary operations, such as copying a reference in a public document, hindering normal academic research and communication.
So, we must use the CSS "unselectable" attribute with caution. We should use this attribute when we need to protect information security and copyright, but when we need to ensure user experience and website interaction, we should try to avoid its use. If we really need to use the "unselectable" attribute, we can use it on certain elements instead of disabling selection of the entire text content. In this case, you can also provide some alternative ways for users to obtain the required information, such as providing download links or copy buttons.
To sum up, we should use the CSS "unselectable" attribute with caution. When we need to ensure the security and copyright of page content, we can use this attribute to help protect the security and copyright of website content; but when we need to ensure user experience and website interaction, we should try to avoid using this attribute, or use something more Flexible ways for users to get the information they need.
The above is the detailed content of CSS is not selectable: is this a good thing or a bad thing?. For more information, please follow other related articles on the PHP Chinese website!

To integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.

React’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 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 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.

The 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 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 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 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.

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),
