Asian languages often employ page layout for characters for better visual formatting using a one or two-dimensional grid. This property controls the size of the character grid for the layout of an element’s text content when the ‘layout-grid-mode’ is set to ‘line’ or ‘both’. Visually, this property has an effect similar to the ‘line-height’ property.

div { layout-grid-mode: line; layout-grid-char: 12px }

Content snapped to a layout grid
