Currently I'm trying to build company-branded desing-system in Storybook. I use addon-docs to generate stories from MDX format for my components and articles about design vision. I want to style generated tags such as h1.
Including custom CSS-stylesheet doesn't seem a good idea to me because it may mix with other components (such as Header that renders the same h1 tag with some className). Of course I may use custom components for documenting, but having MDX in this case has no sense.
From my point of view there is should be some CSS-in-JS styling API for this tags. Have I missed something in Stoybook documentation?
