# BREAKING_STYLE_CHANGE: Breaking style change

> Breaking style change

| Severity | Fault                         | Stage            |
| -------- | ----------------------------- | ---------------- |
| warning  | customer (the source package) | version creation |

## What it means

Compared with the version in production (or the latest version while production points nowhere), a part or a CSS variable of the component was removed, or a CSS variable changed type: page CSS that styles that part or sets that variable no longer applies as before. The version is created; promoting it to production needs allowBreaking.

## How to fix

Keep the part or the CSS variable (with its type), or update the pages' CSS and promote with allowBreaking.
