CSS LAYOUT-GRID-CHAR

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
}

<div style="layout-grid-mode: line; layout-grid-char: 12px">Content
snapped to a layout grid</div>

Possible Values

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.
