text-emphasis-position CSS property sets where emphasis marks are drawn. Like ruby text, if there isn't enough room for emphasis marks, the line height is increased.

/* Initial value */
text-emphasis-position: over right;
/* Keywords value */
text-emphasis-position: over left;
text-emphasis-position: under right;
text-emphasis-position: under left;
text-emphasis-position: left over;
text-emphasis-position: right under;
text-emphasis-position: left under;
/* Global values */
text-emphasis-position: inherit;
text-emphasis-position: initial;
text-emphasis-position: unset;

}
