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
