By default, product pages use a template named meta_catalog/product_detail.html. We can customize this template or create a new template which can be used by a specific product page. In other words, we can create product pages that can look completely different than the rest of the web site which can be used in email or other marketing campaigns.
1. First step is to create a custom template.
2. The next step is to open the product page, locate the Advanced options section and add the custom template name in the Detail template name text field.
3. Save the product.
