Mark error in form using Bootstrap

Question

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

Generally showing the error near where the error occurs is best  i e  if someone has an error with entering their email  you highlight the email input box    This article has a couple good examples   http   uxdesign smashingmagazine com 2011 05 27 getting-started-with-defensive-web-design   Also twitter bootstrap has some nice styling that helps with that  scroll down to the Validation states section  http   twitter github com bootstrap base-css html forms  Highlighting each input box is a bit more complicated  so the easy way would be to just put an bootstrap alert at the top with details of what the user did wrong   http   twitter github com bootstrap components html alerts
