OpenType Features

OpenType features refer to different glyphs or character styles contained within an OpenType font. These include things like ligatures, kerning, fractions, numeral styles, and several others.

Flip the Zero

By default the zero remains with a backslash \ this was done to prevent confusion with the Danish Ø however, when pairing the typeface with a monospace that only supports a forwardslash / zero, this may create a cognitive dissonance problem. On that occasion, you might want to flip the zero:

body {
  font-family: "Lexica Ultralegible", "Atkinson Hyperlegible", Helvetica, Arial, sans-serif;
  font-size: 100%;
  font-weight: 400;
  font-variant-numeric: slashed-zero;
}

Ligatures

Web browsers have ligatures activated by default, we recommend disabling them for heading or large display text.

h1, h2, h3 {
  font-variant-ligatures: no-common-ligatures;
}
