here’s the difference:
Custom Content – when you want to put in images and text, use Custom Content so you have the WYSIWYG editor – it allows you to “switch” back and forth between “design” mode and “source” mode.
Advanced Content – this should be used if you want to add some “script” for a widget for example or “script” for a Quick Search or IDX widget.
Custom Content tends to “add its own coding” when you save. So if you have some script that uses “&” for example…if you put this script into custom content instead of advanced content the platform makes it “&” which is the HTML code for ampersand (&). If you used the advanced content, the “&” would stay “&” in the code.
TRACKING CODE…for those of you using tracking code in your footer template and have it in with custom content, no worries…any tracking code we’ve seen “sticks” just fine.
