Bootstrap4 vs Bootstrap3
Bootstrap4 is the latest version of Bootstrap, which has more specific classes and has turned some related parts into components. Additionally, the size of Bootstrap.min.css has been reduced by more than 40%.
Bootstrap4 has dropped support for IE8 and iOS 6, now supporting only IE9+ and iOS 7+ browsers. If you need to support older browsers, please use Bootstrap3.
