We're happy to share a resource with lots of reusable elements created by our designer friends at IBM. Carbon is the design system for IBM Cloud products. It is a series of individual styles, components, and guidelines used for creating unified UI across all IBM Cloud offerings. The Carbon Design Kit uses the new and free typeface IBM Plex. This kit includes a lot of assets (components, iconography, color palettes, grids, templates) in the Pages section of Sketch on the left side. The Carbon Design Kit is a living and evolving resource you can follow and contribute to on GitHub. Enjoy!
