Bootstrap simplifies the development process mainly through its raster system, predefined components and JavaScript plug-ins. 1. The grid system allows for flexible layout, 2. Predefined components such as buttons and navigation bars simplify style design, 3. JavaScript plug-in enhances interactive functions and improves development efficiency.

Bootstrap is an open source front-end framework developed by Twitter, providing rich CSS and JavaScript components, simplifying the construction of responsive websites. 1) Its grid system is based on a 12-column layout, and the display of elements under different screen sizes is controlled through class names. 2) The component library includes buttons, navigation bars, etc., which are easy to customize and use. 3) The working principle depends on CSS and JavaScript files, and you need to pay attention to handling dependencies and style conflicts. 4) The usage examples show basic and advanced usage, emphasizing the importance of custom functionality. 5) Common errors include grid system calculation errors and style coverage, which require debugging using developer tools. 6) Performance optimization recommendations only introduce necessary components and customize samples using preprocessors

Bootstrap can be integrated in React in two ways: 1) CSS and JavaScript files using Bootstrap; 2) Use the React-Bootstrap library. React-Bootstrap provides encapsulated React components, making using Bootstrap in React more natural and efficient.

There are two ways to use Bootstrap components in React projects: 1) CSS and JavaScript of the original Bootstrap; 2) Use libraries designed specifically for React such as react-bootstrap or reactstrap. 1) Install Bootstrap through npm and introduce its CSS file in the entry file, and then use the Bootstrap class name in the React component. 2) After installing react-bootstrap or reactstrap, directly use the React components it provides. Use these methods to quickly build a responsive UI, but pay attention to style loading and JavaScript
