Revert edit, turns out code previews are already documented in the linked page 🤦🏽‍♀️

-### Code Examples
-
-`/docs/_utils/code-examples.js` is a small 11ty plugin that turns the code examples into previews. It relies on a client-side script of the same name that lives in /docs/assets/scripts and gets loaded into the site’s template.
-
-That takes care of rendering standard code blocks. It supports certain modifier classes:
-- `example`: opts a code snippet in to live demo rendering
-- `no-edit`: removes the codepen button
-- `open`: shows the code snippet by default
-
-Modifier classes are used like this:
-```
-```html {.example .no-edit .open}
-```
-
-That will render an example without the CodePen button and with the code already shown.
