I am a PHP developer. I am trying to change the appearance of the "Log in" form and would like to add special classes to the inputs. I added the "Login" block to the "Homepage" page and would like to make it appear differently here than on other pages. How can I override the class or apply a different template to this one? I Found `BxBaseServiceLogin.php`, and I know how to override that in my module but it looks like that is not handling the actual HTML code for the form.
