The slant axis (slnt)
Of the 558 variable families in the library, 16 have a slant axis (slnt). Slant tilts the letters by the given number of degrees; negative values lean right. The most common range is -8 to 0, used by 6 of them. Sans serifs account for 8. The earliest-dated family with this axis today is Cairo, added in 2019; the date is when the family joined, not when it became variable.
