Language version comparison enables content editors to view and edit two different [language versions](https://docs.kentico.com/k81/multilingual-websites/editing-the-content-of-multilingual-websites.md) of pages side-by-side. This can be convenient when translating website content into multiple languages.

To switch to language version comparison mode in the **Pages** application, select a page and click **Compare** below the content tree.

The system displays a language version comparison toolbar and splits the page editing area below the toolbar into two parts:

- The first displays the page in the language selected in the main selector below the content tree.
- The second displays the language selected on the comparison toolbar.

You can edit both displayed language versions independently at the same time.

The language comparison toolbar provides the following options:

| **Close comparison mode**  | Closes the comparison mode and returns to the standard view of a single language version. You can also close the comparison by clicking **Compare** below the content tree again. |
| -------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Vertical layout**        | Splits the editing area vertically.                                                                                                                                               |
| **Horizontal layout**      | Splits the editing area horizontally.                                                                                                                                             |
| **Synchronize scrollbars** | If enabled, scrollbars in both parts of the editing area are synchronized, resulting in the same sections of both language versions being displayed while scrolling.              |
| **Language selector**      | You can choose which language version of the page is compared with the selected language.                                                                                         |

- If you select a page whose version in the comparison language is not created yet, the standard **New culture version** dialog appears.
- Language version comparison mode is available in both **Edit** and **Preview** mode.
- The comparison mode is also supported for page **Properties,** except for the **Linked pages**, **Related pages**, **Security** and **Languages** tabs (the page properties on these tabs are shared by all language versions).
