No! CoreResources includes archive and single post templates that are built with Elementor Pro. Please note that you will need the Pro version, as CoreResources utilizes Elementor Pro features such as dynamic tags and widget skinning abilities. If your site is built without Elementor, you can still use CoreResources! Also included are WP Customizer options for archive views and single templates. Templates can also be overridden via your own child theme as well. Please note that in this case, you may need a developer to help if you plan on creating custom resource types and their corresponding templates.
