Bear with me here, I'm not 100% sure how to ask this, let alone how to search for some good visual examples to reference, but I'm going to try…
Say you have a list written out in sentence form, where each item is styled for emphasis. Do you then style the commas and punctuation as well.
Here's an example of what I mean:
I understand that in terms of formal writing, although there doesn't seem to be any strict rule on this, it seems that styling the punctuation the same way as the word preceding it is the most common approach (as in the first example). However, from a graphic design perspective, I feel like both approaches leave something to be desired.
In the first example, at first glance "kittens" and "bunnies" almost appear to be sort of the same item, since there's not really anything separating them. I mean, I know there's a comma separating them, but they still look lumped together.
But conversely in the second example the alternating style of the commas looks weird and out of place.
All of this to ask: is there an established convention on this in graphic design? If not, which option would a professional choose and why?
