We mostly prefer notification in our project, because for example if admin add new record and we need to display notification with success alert, info elert etc when comes error then display error notication. So if you are using bootstrap then you can use growl js plugin, you have to just add js, no need to add css file.
In this example i use bootstrap-growl.js plugin that provide several notification type like warning, success, info, error etc and several function. In my previous post also added using toastr.js, you can also see here : Jquery notification popup box example using toastr JS plugin with demo. bootstrap-growl plugin you can use easily with bootstrap and very customize. You can run bellow example and you can see how it works and pretty good.
