For our Outreach documents, why isn't there any HTML content when looking at the Source?
When you first create a new document and click the HTML tab and select Begin With Blank Content option. If you click the Source tab at the bottom, you can see some HTML code that includes a !DOCTYPE statement and opening and closing <head> and <body> tags.
From the Design tab, if you apply a template to the blank document, you will see the template content display. Now, though, when you click to Source mode, the HTML code is gone and the Source page is blank.
The reason for this is that when a template is applied to a document, the HTML code for the <head> and <body> tags is associated with the template and is no longer associated to the document content. When a template is applied, the only HTML that will display on the Source tab is the HTML associated with the editable content of the document. Once you add some actual content for the document, you will see the corresponding HTML on the Source tab.
