I am learning react.js and I need to make my app responsive. What should I use? Bootstrap or react-bootstrap? Can I use Bootstrap in react? Or I need to use react-bootstrap? What's the difference
react-bootstrap is a UI library of components similar to material-ui or a lot other UI libraries, while Bootstrap alone is a collection of CSS classes + HTML UI components.
You are free to choose between them, react-bootstrap or Bootstrap by your choice.
