margin
Think of a margin like the crust on a pizza. The crust is the edge that goes all around the pizza, keeping all the yummy toppings from falling off. Just like that, a margin is the space around the main part of a page, like the words in a book, making sure everything stays neat and tidy.
Another way to think about a margin is like the fence around a playground. The fence keeps the kids safe inside while they play. The margin on a piece of paper keeps the important stuff, like your drawings or writing, safe and inside the lines.
Imagine you have a picture frame around your favorite photo. The frame is like a margin, because it surrounds the picture and makes it look nice and complete. Without the frame, the picture might look like it’s missing something. Similarly, a margin helps to make things look finished and organized.
Finally, think of a margin as the space you need to give your toys on a shelf. If you push them too close to the edge, they might fall. A margin gives your toys some space so they stay safe and don’t fall off.
