Bootbox.js is a small lightweight library to help you create responsive popups/modals which uses bootstrap theme. I am listing few things I like about Bootbox.Js 1. Very lightweight when minified and bundled. 2. No extra CSS required. Fully compatible with bootstrap 3.0.0+ and JQuery 1.9.1+ 3. Can handle alert, prompt box, confirm dialog boxes. Even customization is possible for buttons, inputs, dropdowns etc. 4. Supports callback which is super useful in some cases where you need to handle some tasks after certain actions. 5. Can be used as a busy loader. 6. It doesn't affect already existing modals. 7. All events related to bootstrap modal can be hooked up with the bootbox modal. 8. No HTML coding required 9. Free and open source. So overall it is a very nice and powerful plug in to boost your product and productivity.
