No, I don't believe there is such an option. However, if you're dealing with blocks on a page and styling them, there is an option called "Custom Templates", which allows you to choose a pre-defined alternative rendering of that block. Some blocks have these, others don't.
Or, you can always add your own custom CSS to each block through the "Design" option.
