Understanding overflow: auto vs overflow: scroll in CSS
overflow: auto automatically adds scrollbars only when content overflows the container. If the content fits, no scrollbars appear.
overflow: auto; – Scrollbars appear only when the content overflows the container.
overflow: scroll; – Scrollbars are always visible regardless of content size.
Use auto for a cleaner UI with conditional scrollbars, and scroll when you want scrollbars to always be present.
