gatsby-theme-ui-layout

Gatsby theme for adding shadowable layouts to multiple Gatsby themes for composition.

npm i gatsby-theme-ui-layout

In your theme, import and use the Layout component, which does not include any default layout.

// example page template
import { Layout } from 'gatsby-theme-ui-layout'

export default (props) => (
  <Layout {...props}>{/* your theme content goes here */}</Layout>
)

End-users of a theme that is built with gatsby-theme-ui-layout can shadow the same Layout component to customize the page layout.
