Final answer:
Liquid tags in template languages like Liquid used by Shopify are wrapped in the characters {{ }} for outputting data, whereas {% %} is used for logic and control flow.
Step-by-step explanation:
Liquid tags are a part of a template language used in various web applications, including Shopify. They are used for adding dynamic content to static pages. When it comes to wrapping liquid tags, the correct characters are {{ }} for outputting content. These tags are often confused with {% %}, which are actually used for logic and control flow in Liquid. It is important to differentiate between the two because they serve different purposes within the template language.
