Timelines can be very useful for introducing the events of a history. Using a timeline greatly reduces the fatigue of reading content. In this code, this vertical timeline can do the same for us. Each item in this timeline includes a photo. Each photo zooms in slightly at the beginning of the display. At the end of the text, there is an arrow pointing down, which, when clicked, displays the next item in the timeline.
