Best practices for managing WordPress templates include:
Keeping templates organized and named clearly for easy identification.
Regularly backing up your site before making changes.
Take advantage of the block editor to customize templates directly within WordPress. This allows for a visual and modular approach to editing, making it easier to design and arrange content without touching the code.
If you create custom layouts that you might want to reuse, save them as block patterns. This allows you to apply them quickly to other pages or posts.
