# Function: propertiesCss()

> **propertiesCss**(`theme`, `options?`): `string`

Beta

The document-global `@property` registrations, with no declarations. Load this once per document;
every theme sheet below is declarations only, so loading a second theme cannot clobber it.

## Parameters

### theme

[`Theme`](../../../../packages/core/src/type-aliases/Theme.md)

### options?

[`ScopedCssOptions`](../interfaces/ScopedCssOptions.md) = `{}`

## Returns

`string`
