overflow-y

The overflow-y CSS property sets what shows when content overflows a block-level element’s top and bottom edges. This may be nothing, a scroll bar, or the overflow content. This property may also be set by using the overflow shorthand property.

Try it

Syntax

/* Keyword values */ overflow-y: visible; overflow-y: hidden; overflow-y: clip; overflow-y: scroll; overflow-y: auto; /* Global values */ overflow-y: inherit; overflow-y: initial; overflow-y: revert; overflow-y: revert-layer; overflow-y: unset; 

The overflow-y property is specified as a single keyword value.

If overflow-x is hidden , scroll , or auto and the overflow-y property is visible (default), the value will be implicitly computed as auto .

Values

Overflow content is not clipped and may be visible outside the element’s padding box at the top and bottom edges. The element box is not a scroll container.

Overflow content is clipped if necessary to fit vertically in the elements’ padding box. No scroll bars are provided.

Overflow content is clipped if necessary to fit vertically inside the element’s padding box. Browsers display scroll bars in the vertical direction whether or not any content is actually clipped. (This prevents scroll bars from appearing or disappearing when the content changes.) Printers may still print overflowing content.

Overflow content is clipped at the element’s padding box, and overflow content can be scrolled into view. Unlike scroll , user agents display scroll bars only if the content is overflowing, hiding scroll bars by default. If content fits inside the element’s padding box, it looks the same as with visible , but still establishes a new block-formatting context.

Note: The keyword value overlay is a legacy value alias for auto . With overlay , the scroll bars are drawn on top of the content instead of taking up space.

Formal definition

Initial value	visible
Applies to	Block-containers, flex containers, and grid containers
Inherited	no
Computed value	as specified, except with visible / clip computing to auto / hidden respectively if one of overflow-x or overflow-y is neither visible nor clip
Animation type	discrete

Formal syntax

overflow-y =

overflow

The overflow CSS shorthand property sets the desired behavior when content does not fit in the parent element box (overflows) in the horizontal and/or vertical direction.

Try it

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

/* Keyword values */ overflow: visible; overflow: hidden; overflow: clip; overflow: scroll; overflow: auto; overflow: hidden visible; /* Global values */ overflow: inherit; overflow: initial; overflow: revert; overflow: revert-layer; overflow: unset; 

Values

Overflow content is not clipped and may be visible outside the element’s padding box. The element box is not a scroll container. This is the default value of the overflow property.

Overflow content is clipped at the element’s padding box. There are no scroll bars, and the clipped content is not visible (i.e., clipped content is hidden), but the content still exists. User agents do not add scroll bars and also do not allow users to view the content outside the clipped region by actions such as dragging on a touch screen or using the scroll wheel on a mouse. The content can be scrolled programmatically (for example, by setting the value of the scrollLeft property or the scrollTo() method), in which case. The element box is a scroll container.

Overflow content is clipped at the element’s overflow clip edge that is defined using the overflow-clip-margin property. As a result, content overflows the element’s padding box by the value of overflow-clip-margin or by 0px if not set. Overflow content outside the clipped region is not visible, user agents do not add a scroll bar, and programmatic scrolling is also not supported. No new formatting context is created. To establish a formatting context, use overflow: clip along with display: flow-root . The element box is not a scroll container.

Overflow content is clipped at the element’s padding box, and overflow content can be scrolled into view using scroll bars. User agents display scroll bars in both horizontal and vertical directions if only one value is set, whether or not any content is overflowing or clipped. The use of this keyword, therefore, can prevent scroll bars from appearing and disappearing as content changes. Printers may still print overflowing content. The element box is a scroll container.

Overflow content is clipped at the element’s padding box, and overflow content can be scrolled into view. Unlike scroll , user agents display scroll bars only if the content is overflowing and hide scroll bars by default. If content fits inside the element’s padding box, it looks the same as with visible but still establishes a new formatting context. The element box is a scroll container.

Note: The keyword value overlay is a legacy value alias for auto . With overlay , the scroll bars are drawn on top of the content instead of taking up space.

Description

Overflow options include hiding overflowing content, enabling scroll bars to view overflow content or displaying the content flowing out of an element box into the surrounding area, and combinations there of.

The following nuances should be kept in mind while using the various keywords for overflow :

• Specifying a value other than visible (the default) or clip for overflow creates a new block formatting context. This is necessary for technical reasons; if a float intersects with a scrolling element, it would forcibly rewrap the content after each scroll step, leading to a slow scrolling experience.
• For an overflow setting to create the desired effect, the block-level element must have either a set height ( height or max-height ) or white-space set to nowrap .
• Setting one axis to visible (the default) while setting the other to a different value results in visible behaving as auto .
• The JavaScript Element.scrollTop property may be used to scroll through content in a scroll container, including when overflow is set to hidden .

Formal definition

• overflow-x : as specified, except with visible / clip computing to auto / hidden respectively if one of overflow-x or overflow-y is neither visible nor clip
• overflow-y : as specified, except with visible / clip computing to auto / hidden respectively if one of overflow-x or overflow-y is neither visible nor clip

Formal syntax

overflow =
[ visible | hidden | clip | scroll | auto ]

Accessibility concerns

A scrolling content area cannot be scrolled by a keyboard-only user, with the exception of users on Firefox (which makes the container keyboard focusable by default).

As a developer, to allow non-Firefox keyboard-only users to scroll the container, you will need to give it a tabindex using tabindex=»0″ . Unfortunately, when a screen reader encounters this tab-stop, they will have no context for what it is and their screen reader will likely announce the entirety of its contents. Giving it an appropriate WAI-ARIA role ( role=»region» , for example) and an accessible name (via aria-label or aria-labelledby ) can mitigate this.
