The
overflow declaration tells the browser what to do with content that doesn't fit in a box. This assumes the box has aheight: if it doesn't, it becomes as high as necessary to contain its contents, and the overflow declaration is useless.
You can assign four values to overflow and they should give the following results:
visible: the content flows out of the box.hidden: the overflowing content is completely hidden, not accessible to the user.auto: show scrollbars where necessary (horizontal or vertical or both).scroll: always show horizontal and vertical scrollbars, regardless of whether they're necessary. This value is never used; you generally want auto.overlay: non-standard value only supported by the WebKit-browsers that does the same as auto.
