A key component of your wireframes should test which aspect?

Interaction is a key component of wireframes because wireframes are primarily designed to illustrate how users will interact with a website or application. They serve as a blueprint for both usability and functionality, allowing designers and stakeholders to visualize the navigation paths, button placements, and user flow without getting distracted by visual design elements like colors and images.

Testing interaction through wireframes helps gather feedback about the user experience, identifying potential issues with navigation or engagement before any development takes place. This focus on interaction is crucial for ensuring that the final product is intuitive and user-friendly, addressing how users will move through the interface and perform tasks effectively.

In contrast, while content layout also plays an important role in wireframing, it is not the sole focus. Other aspects, such as color schemes and code syntax, are not typically considered at this stage, as they pertain to the visual design and development phases rather than the early conceptual framework of interaction.
