Instead of using a simple timeline, use an animated timeline to enhance the appeal of your work. Like the code below, we have a horizontal timeline that displays text if we click on each timeline. It can be used when we want to show the roadmap of something as a question and answer and the user can see the answer of each time by clicking on each.
