Those terms let me know that the value given is going to modify some other value. I’m guessing that ‘factor’ is a bit better for those with less math/programming knowledge.

"unit" or "increment" also indicate that it's locked to certain multiples.

But the properties refer to ‘height’ and ‘width’ so it’s not very clear that it’s not the element’s height and width being modified. So instead of ‘snap-height’ I suggest the property be named ‘line-height-factor’.

So if I set ‘line-height’ it clears the ‘line-height-factor’ value - I don’t have to hunt down the new property to find out why my line-heights aren’t what I specified. We could at some point in the future make ‘line-height-factor’ settable in the ‘line-height’ shorthand, if that proves useful.

In this case there isn’t a property that directly sets available inline size, but one could be added as a shorthand for that and ‘line-width-factor’ in the future if it’s needed.

I like these.  Tying it into line-height makes a lot of sense, and
makes it clearer that this is just an inline-affecting property.
