Thanks! That did clear up a thing or two on the Illustrator side of it. I wish I knew more (anything really) about code though. I bet there is some useful info in there, I just can’t do much with it.
I have been successful in using svg as my featured image and it looks amazing, but I have had trouble getting them to appear as media in my portfolio item posts. It would be very helpful if I could get them to work because so much of what I show is vector-based and the fuzzy edges really detract from their quality, particularly on a retina-level resolution screen.
