This module seems to work fine; however, its inclusion of a default font percentage size means that it destroys any variable font sizing established via CSS on a page. That is, if a page includes elements in a number of variable font sizes (e.g. main text at 100%, headings at 125%, special list items at 80%, and so on), this module will convert *all* these to the default size setting of the module - effectively destroying the page design. As there does not appear to be any way *not* to set a default size (if one removes the setting, it simply defaults to 100% on module save), it effectively makes the module unusable on CSS designed pages where there is more than a single font size in use (which is generally all pages).
