Display Messages notifications inside a div box

When the user enter a not valid credentials it print this notificaitons message:

Sorry, your password was incorrect.<br/> Please double-check your password

But this doesn't look good when it is printed:

I want it to be printed between the Login button and the Forgot password. Like that:

So theoretically the white box should expend to the bootom to leave so place for the notifications message
