Similar to Content Sections, Code Snippets can be used to break up your Pages, keeping different aspects of your Pages separate. Content Sections are mainly used for content whereas Code Snippets are mainly used for code snippets, such as head scripts.
Where can you find Code Snippets?
While viewing your Site Admin, use the left-hand menu to click "Site Manager" and expand the sub-menu. Next click on "Code Snippets" to view a list of existing Code Snippets on your Site.
