Content Macros
Use the content macros to build your login page.
You can create a basic login page using only three content macros: CL_HEADER, CL_PROMPT, and CL_FOOTER. The macros are added to the login template as follows:
<%CL_HEADER%>
<%CL_PROMPT%>
<%CL_FOOTER%>
Note that the content macros are not mandatory. If a macro is not specified in the template, the content associated with the macro is not added to the login page. For example, if a template specifies CL_HEADER and CL_PROMPT, but not CL_FOOTER, the footer is not included in the login page. Optionally, you can add your own footer.
If you create a custom login page, and the login template where customizations are defined and cannot be found, the login page defaults to the basic login page.
