Conversion method: 1. Add the "text-transform: uppercase;" style to the English element, which can turn all English letters into uppercase; 2. Add "text-transform:capitalize;" to the English element Style that capitalizes the first letter of every word in English text.

css to convert English lowercase to uppercase
In css, you can use the text-transform attribute to convert lowercase English letters (text) for capital letters.
can be divided into two situations:
All English letters become uppercase: use the "
text-transform: uppercase;
" styleThe first letter of each word in English text is capitalized: use the "
text-transform: capitalize;
" style
Implementation example:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Document</title> <style> p { font-variant: small-caps; /*把段落设置为:小型大写字母字体(即文字的大小不变,只不过文字都变成了大小字母)*/ } span[first] { text-transform: capitalize /*使每个单词的首字母变为大写。*/ /* capitalize可以使每个单词的首字母变为大写 */ /* uppercase 定义仅有大写字母 */ /* lowercase 定义无大写字母,仅有小写字母 */ /* inherit 规定应该从父元素继承 text-transform 属性的值。 */ } span[second] { text-transform: uppercase /*把所有的字母都变成大写。*/ /* capitalize可以使每个单词的首字母变为大写 */ /* uppercase 定义仅有大写字母 */ /* lowercase 定义无大写字母,仅有小写字母 */ /* inherit 规定应该从父元素继承 text-transform 属性的值。 */ } </style> </head> <body> <p>hello</p> <span first>heloodj sdKUv dIfvh</span> <hr> <span second>heloodj sDFuv difvh</span> </body> </html>
Description: text-transform attribute
The text-transform attribute controls the case of English text.
Setable attribute values:
Value | Description |
---|---|
none | default. Text that defines standards with lowercase and uppercase letters. |
capitalize | Every word in the text begins with a capital letter. |
uppercase | Definition only uppercase letters. |
lowercase | Definition has no uppercase letters, only lowercase letters. |

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.

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 Strict Mode is a development tool that highlights potential issues in React applications by activating additional checks and warnings. It helps identify legacy code, unsafe lifecycles, and side effects, encouraging modern React practices.
