Is there example best practice code for creating Visual Fragments

@robertpc4 Depends on the structure and layout of the email that you're building setup the visual fragment accordingly. Also, identify which parts of the fragments are customizable.

An example would be setting up the header and footer as fragments that can be reused while building the content templates.
