# Block types: code, callout, cta, image, mascot

Published: 2026-02-25

A short tour of every custom Portable Text block type the Nebion blog supports out of the box. Use these in your own posts.

The Nebion blog supports five custom block types beyond the standard Portable Text blocks. They are inserted as raw JSON nodes in the body — the slash-command UX in admin will arrive once we publish the plugin as a package.

## Code block

```yaml
recipe: manual
deploy:
  - bin/build.sh
  - bin/release.sh
destroy:
  - bin/teardown.sh
```

## Callout

> Heads up: Callouts come in four tones: info, warning, success, danger. Pick the one that matches the gravity of the message.

> Production deploys propagate to the edge in seconds — but cache invalidation can take longer. Plan accordingly.

## CTA card
