overflow-y

Defines how a block level element should handle content that goes beyond its y-axis boundary.

Syntax

overflow-y: <value>;

where <value> can be one of the following:

• visible: the default value. No content will be clipped and a scrollbar will not appear.
• hidden: content will be clipped and no scrollbar will appear.
• scroll: content will be clipped and a scrollbar will appear.
• auto: content will be clipped if it does not fit in the containing block, and a scrollbar will appear if it does.
• Keyword values: initial, inherit, revert, unset.

Example 1

Clip any content that overflows without providing a scrollbar to view overflow content.

.view-box {
  overflow-y: hidden;
}

Example 2

Provide a scrollbar and clip any content that overflows.

.view-box {
  overflow-y: scroll;
}

Example 3

Provide a scrollbar only if overflow content exists.

.view-box {
  overflow-y: auto;
}
