Change CSS Class on Focus

Change CSS Class on Focus

Hello,

I have a form where each field is inside a div.
So I have the following code to highlight the div on mouse over and remove it on mouse out:
  1.   $('form div.Field').hover(function () {
  2.     $(this).addClass('Hover');
  3.   }, function () {
  4.     $(this).removeClass('Hover');
  5.   });
But what I really need is:
- Add CssClass Hover when any form element (input, select, ...) inside the div is focus;
- Remove CssClass Hover when the form elements inside the div stop being on focus.

Do you understand?

How can I do this?

Thanks,
Miguel
