“Monospace” (MONO
in CSS) is an axis found in some variable fonts, which adjusts the glyphs from a proportional width to a fixed width. In monospaced typefaces, or variable fonts set to a monospaced style, all glyphs take up the same amount of horizontal space.
The Google Fonts CSS v2 API defines the axis as:
Default: | Min: | Max: | Step: |
---|---|---|---|
0 | 0 | 1 | 0.01 |
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.
