orphans
CSS orphans property
The orphans property is used to specify the minimum number of lines of a block-level container that can be left at the bottom of a page or column.
An orphan is the first line of a paragraph that appears alone at the bottom of a page and the paragraph continues on a following page.
The orphans property is commonly used with the @media rule for specifying the number of orphans which are allowed at the end of a page. It can also be used in multi-column layouts for web pages and digital documents. In this case, it will specify the number of lines which are allowed at the end of a column.
The orphans property has a sister property: the widows, which specifies the number of lines that come at the beginning of the following page/column.
