The JSSTag.lineHeight property corresponds to the line-height CSS property.
This value specifies the distance between the baselines for adjacent lines; more accurately, it indicates the minimum distance, because an object larger than the line height value will cause lines to be leaded further apart to accommodate the item within the display.
The following values are meaningful in this property:
A numeric line height measured in points
A value in pixels
A distance in mm
A percentage of the parent line height value
The default value for this depends on the user preference settings for font sizes.
This value is inherited from its parent container element.
