Whenever I write a VF Page, I see the "loose.dtd" file being included automatically in the HTML code(Firebug/Developer Console).
DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"
Please suggest an approach to remove this, as it makes my HTML code to conflict with IE.
