Letter-spacing values declared in % in Design mode should be represented in em in Dev mode, instead of px or rem. em units are relative to the font size, whereas px and rem are not.

For example, a letter-spacing value of 2% should be represented in CSS as .02em. (You can’t declare letter-spacing in % units in CSS, so this is why we must use em.)

Currently, when you view the code in Dev Mode, the only unit options you are given are rem or px, which are two static units, not relative units. This means you end up outputting random values like “letter-spacing: 0.1125rem;” which doesn’t scale relative to your font size on the front-end.

This causes many headaches for me and my developers. Would love to see this updated!
