# tools.sign.fonts

Part of [Tools](https://kernstra.com/docs/web-sdk/config/tools) in the Kernstra Web SDK 1.0.0 configuration reference.

- Type: `readonly SignatureFont[]`
- Default: `SIGNATURE_FONTS`
- Page: https://kernstra.com/docs/web-sdk/config/tools/sign-fonts

Faces the Type tab offers. Each `SignatureFont` is `{ family, label }`: `family` a CSS font-family value — load the face yourself (`@font-face`) — and `label` the name shown beside the preview. `fonts` replaces the Type tab's faces, in order; an empty list keeps the default. The built-in faces' names ("Standard", "Script", …) follow the viewer's language when you pass the `SIGNATURE_FONTS` objects themselves — spread the constant; a face you describe yourself shows the `label` you gave it.
