Imagine you have a bunch of toys that you want to arrange in a straight line, from biggest to smallest. To do this, you can line them up one after the other, so that they form a tall stack on top of each other. This stack is similar to a column. A column is a tall, vertical structure that is made up of smaller parts stacked one after the other. Columns are often used in architecture and design to support the weight of a building or to create a decorative effect. Think of columns like a bunch of toys stacked on top of each other, creating a tall and sturdy structure.
