I am exploring child templates for the first time and enjoying the power that they offer, all my new projects will now be child themes based on the default theme.
However I've come up against my first issue, for a design that involves full width headers and footers, I need the mark-up for these sections to reside OUTSIDE of the wrapper container.
Right now all the content is inside the main wrapper, can I use filters or hooks to relocate the header and/or footer to be outside the wrapper, only using functions.php?
Or is my best bet to create new template files that define the new HTML hierarchy?
