More Details for overflow-block
overflow-block
The overflow-block
CSS property sets what shows when content overflows the block start and block end edges of a box. This may be nothing, a scroll bar, or the overflow content.

property maps to overflow-y
or overflow-x
depending on the writing mode of the document.
Syntax
/* Keyword values */ overflow-block: visible; overflow-block: hidden; overflow-block: scroll; overflow-block: auto; /* Global values */ overflow-block: inherit; overflow-block: initial; overflow-block: revert; overflow-block: unset;
The overflow-block
property is specified as a single keyword chosen from the list of values below.
Values
visible
Content is not clipped and may be rendered outside the padding box's block start and block end edges.
hidden
Content is clipped if necessary to fit the block dimension in the padding box. No scrollbars are provided.
scroll
Content is clipped if necessary to fit in the block dimension in the padding box. Browsers display scrollbars whether or not any content is actually clipped. (This prevents scrollbars from appearing or disappearing when the content changes.) Printers may still print overflowing content.
auto
Depends on the user agent. If content fits inside the padding box, it looks the same as visible
, but still establishes a new block-formatting context. Desktop browsers provide scrollbars if content overflows.
