I want know that how to change my login page setting in wordpress... for example. this is one page where can show the login link is "http://room.pk/wp-login.php?action=login" & Register "http://room.pk/wp-login.php?action=register". I want to change the login & register link in whole site, if user click on login & register link so it is automatically redirect with "http://room.pk/wp-content/plugins/wordpress-social-login/authenticate.php?provider=Facebook"
I dont think there is a way to do this with css. I think you will have to use a plugin that will allow you to change those pages and then you can if the plugin allows it add custom css in the plugin itself. Or you could mess around with wordpress files trying to edit them but i never tried it.
