Customize serverFacts with CSS

I’m displaying serverFacts on my app’s admin page but I’d like to change the way it looks via CSS. I can obviously just change the list tags with CSS, but that will change them in my entire app. I’d like to add a class (serverFacts?) to each of the list tags in the facts package, but I’m not sure how to go about overriding the facts.html file in the internal serverFacts package. Or do I need to ask for this change from MDG. I’d be happy putting in a pull request and doing the changes myself. Any suggestions as to how to proceed?
