“Softness” (SOFT
in CSS) is an axis found in some variable fonts. At the end of this axis, letterforms become more soft and rounded.
The Google Fonts CSS v2 API defines the axis as:
Default: | Min: | Max: | Step: |
---|---|---|---|
0 | 0 | 100 | 0.1 |
In the Fraunces typeface, the softness axis can turn the sharp and high-contrast serifs into bubble-like forms. At its softest, Fraunces starts to resemble the style of typefaces such as Souvenir or Bookman.
In line with the current CSS spec, the four-character code for this axis should be referenced in UPPERCASE (as only the five axes registered in the OpenType format specification should appear in lowercase). Also, when using the Google Fonts API, the lowercase axes have to appear first in the URL, followed by the uppercase, each in alphabetical order.
