A timeline arranges events in the order they happened or are expected to happen. It is like a line in a history book, with each point marking one moment and its short description.
For example, a delivery page might show “Order placed,” “Packed,” and “On the way.” Seeing the steps in order helps someone understand what has already happened and what may come next.
Use a timeline when the order of events matters. Keep each step brief, and make unfinished or delayed steps easy to tell apart from completed ones.
