The CSS overflow property specifies the behavior that occurs when an element's content overflows the element's box.

Question

someone explain it more why we use this item?!and when?

Answer 1

Let's say you have a <div> tag, and the text, images you put in it doesn't fit in, that's where you use the overflow rule, whether you show it, hide it, or have a scrollbar in place so you can view the cropped content (part of the content that is out of the <div> body).
