the period of time during which something changes from one state or stage to another.
Design is not just about visuals and aesthetics. Design is also about how it interacts and functions at different states of time. Transitions help users understand the pace and flow of an interface. Nothing feels more unnatural than a sudden change, because sudden changes just don’t exist in the real world. One such example is the toggle menus. Users associate the “plus” symbol with the action of adding content or expanding an element. By rotating it by 45°, the plus becomes a cross, an interface element widely understood to mean “close” The transition is subtle but has a big impact on orienting the user.
Babies grow and change at an astounding pace, and every month brings new and exciting developments. When a baby is born, there is a smooth transition of growth every year as a part of their life. Now, during the course of a child’s life, change is inevitable. Families move, siblings are born, school begins, and, consequently, transitions happen. Knowing about children’s development can help parents and guardians understand how children respond to transition.
