Using hooks for additions and overrides is recommended. You could also override templates the regular way, by adding “header.php”, “page.php” etc to your child theme folder.
Why should I consider using hooks instead of template overrides?
Two obvious reasons:
- If you’re just going to do a tiny tweak, it is just easier. Check out available actions, available filters and pluggable functions
- If you want to change, remove or add something to the output of for example the post feed, you will benefit from Express 2 doing the same action on all post feeds: Search results, archive, front page posts and so on. Easier than overriding all those templates.
