CSS overflow-y Property

Description

The overflow-y CSS property is used to control the vertical overflow behavior of an element when its content exceeds its defined height. It specifies how the content that overflows the element's vertical boundaries should be handled. You can set it to various values such as "visible" (default, content overflows the box), "hidden" (content is clipped and not visible), "scroll" (scrollbars appear when content overflows), or "auto" (scrollbars appear only when necessary). This property is particularly useful for maintaining the layout and appearance of web pages when dealing with long or dynamic content within a fixed-size container.

Interactive Demo

The rusty swing set creaked a lonely lullaby in the twilight, shadows lengthening like grasping fingers across the dew-kissed grass. A lone dandelion seed, adrift on the breeze, whispered secrets of faraway fields, of dandelion suns and galaxies spun from fluff. Somewhere, beyond the veil of dusk, a coyote laughed, echoing through the stillness like a forgotten memory.

Syntax

Values

  • visibleContent is not clipped and scroll bars are not added. Elements are clipped to the size of the containing window or frame.
