Question about CSS feature

[Biffy]

I have a client that just upgraded to 5.5.

In the Miva CSS field there are some CSS styles defined. One of them is an H1 tag that is a 2 pixel background image.

Did this h1 style come from Miva? If not, how could it have gotten in there?

I have much more important things to use h1 for than a 2 pixel background image!

My bad. This was a domain transfer, not a 5.5 update. The CSS was put in there by the client on the old domain.
