+ The mixin also accepts a (not required) second parameter (a number smaller than 1 that varies with the font-family value) that improves the crop effect.
+ Since this additional parameter depends on the font-family only (it is not affected by font-size or font-weight or line-height), a good idea would be to define a CSS variable for each one of your font families.
+ You can then use that variable to call the lhCrop mixin; this way, if you need to change your font-family, you’ll only need to update the  value of that variable with no need to modify the mixin calls.
+ In the 📁 custom-style/_typography.scss file, you find this variable defined for the primary font (--font-primary-capital-letter). Its default value is one, so make sure to update it according to your font-family.
