Indent style is like how we start a new paragraph in a story. When we write a new paragraph in a story, we usually start it a little bit inside the page, like a little bump or a small space. This is called an indent.
Now, in programming, we also use indent style. It's like a new paragraph, but instead of tell a story, we write code. When we write a new code block, like a function or a loop, we indent it. It helps us see which code block is inside of which code block. It's like making little steps inwards, so we know we're going deeper into our programming story.
Some people like to indent their code with just one space, while others like to use a tab- which is like a big space. It's kind of like how some people like using big crayons to color and write, while others like little crayons. The most important thing is to stay consistent with whichever indent style we choose, so our code is easy to read and understand.
