I’ve started using Bootstrap in order to achieve a nice page design without resorting to GWT (the backend is made in java)
For my login screen I copied this example. Now I want to mark an error, for instance, that the username was left empty. So I was wondering what is the procedure in the Bootstrap framework for this. Or maybe if there are examples showing the form with error.
I’m not sure if the idea is to show the error message inside the input element with a red color, or to show it below the input element, or maybe with a popup?
