I need change login template (login in silveerstripe admin area). I create Layout/security_login.ss but i want modify also header and footer that are inherited from Page.ss .
Is it possible?
Maybe by creating a new page where users log in LoginPage extends Page and using
LoginPage.ss to style the header and footer?
you can create a "Security.ss" file in your template folder. Or make a copy of /theme/templates/Page.ss and name it Security.ss.
