The line-clamp as a shorthand property for block-overflow

The CSS line-clamp property is a shorthand for block-overflow and max-lines properties. It truncates text at a specific number of lines. It limits the text, after you tell it the desirable number of lines, adding an ellipsis after the last word or portion of a word that is demonstrated.
