gatsby-remark-highlight-code

Adds stylish cards and syntax highlighting to code blocks in markdown files using the @deckdeckgo/highlight-code Web Component.

This code highlighter is developed with Stencil and use Prism.js under the hood.

The inspiration for the design of the "Macish" cards comes from the amazing carbon, a tool to create and share beautiful images of your source code, and for the "Ubuntu-ish" from the article of Cody Pearce.
