# Introduction

> **Note:** The terms popup and lightbox refer to the same element. While the editor and dashboard now refer to it as a [popup](https://support.wix.com/en/article/studio-editor-using-popups), the API methods continue to use the term lightbox for backward compatibility. The documentation uses both terms accordingly.

To learn more about popups, see the [Hello Popups](https://dev.wix.com/docs/coding-examples/getting-started/hello-world/hello-popups.md) example page.

The APIs in `@wix/site-window.Lightbox` can only be used in frontend code.
