I would like to create a custom opt-in box for my website sidebar. I know how to put the code in...but I am looking for a "pretty" look. I am just not sure where to put the css that is associated with the opt-in and how to reference it in the widget.
I have image, css, and html that is associated with the box I want to use. I know the html goes in the widget box, and I can rename the images links so that it knows where they are, but what about the css?
Any help would be appreciated!
