What text can be edited with the CMS?
If there is text content anywhere on the webpage, then the CMS can manage it. This means that you can insert to supported text macros into any 3rd party stack and many RapidWeaver settings and it can be managed by both Total and Easy CMS.
If the text is inserted into an external file from the actual webpage (css,js,php, etc.) then it cannot be edited by the CMS.
