You have learned how to use Smarty tags and refine them with a parameter so far. You have also ported an entire HTML template to CMS Made Simple. However, if you would like to create professional sophisticated designs, you will need more knowledge about Smarty. With the powerful combination of Smarty and HTML, there are no limits to the flexibility of the sites you design.
Smarty variables are much simpler than complex Smarty plugins. They are placeholders that contain plain information about the actual page ID, page alias, or position of the page in the hierarchy. Some Smarty variables that you are not aware of, are already defined in your template. You do not need to know or remember all of them if you know how you can figure out their names and values.
