I used Murray's solution successfully though I don't understand why list-style-image doesn't work. I also preferred not to mess with the fluid stylesheet. Targeting <li> seems better than <article> since I'll be using lists on several pages of the site, in spite of the extra coding here. Though I'm always open to a more streamlined method.
The next thing I'm noticing is that margin/padding on the right of the list items doesn't work as intended. Whatever the browser width, the list items want to be wider than paragraphs.
