Asian languages often employ page layout for characters for better visual formatting using a one or two-dimensional grid. This property controls the grid length granularity when the ‘layout-grid-mode’ is set to ‘line’ or ‘both’. Visually, this property has an effect similar to the ‘line-height’ property.
<div style="layout-grid-mode: both; layout-grid-line: 10px">Content
snapped to a layout grid</div>
none: No line grid is used.
auto: The largest character in the font for the current element is used to determine the character grid.
[length]: Refers to either an absolute measurement or a relative measurement based on the current element’s font size.
[percentage]: The percentage is relative to the height/width of the parent element.
