What is a Shopify theme?

A Shopify theme serves as the foundation for the visual appearance and structural layout of an online store created using the Shopify platform. It encompasses various design elements, such as fonts, color schemes, and positioning of content, ensuring that the store has a cohesive look and feel. By utilizing pre-designed templates, Shopify themes enable store owners to customize their storefronts efficiently without needing extensive coding knowledge. This allows for a variety of aesthetics and functionalities, helping merchants to create unique online shopping experiences that resonate with their brand identity.

The other options do not accurately reflect the role of a Shopify theme. For example, while marketing materials like images and videos are essential for promoting a store, they aren't what defines a theme. Content strategy pertains to how information is organized and presented but doesn’t directly relate to the design and layout aspects. Lastly, guidance on building physical stores falls outside the scope of what a Shopify theme encompasses, which is focused exclusively on online commerce.
