Page design refers to the process of designing individual pages for an application. This typically involves creating visual elements, such as layout, typography, and colour, as well as arranging and organising content in a way that is clear and intuitive for users.
On the other hand, multi-step flows refer to the sequence of pages that a user encounters when using a application. This can also be referred to as the user flow or the user journey. The goal of multi-step flows is to create a smooth and intuitive experience for the user as they navigate through the application, allowing them to easily access the information they need. This typically involves carefully designing the interactions and actions that users take on each page, to create a cohesive and logical experience.
In summary, page design focuses on the design of individual pages, while multi-step flows focus on the user journey and how pages fit together to form a cohesive experience .
Both are important aspects of UX design.
