Language version comparison enables content editors to view and edit two different [language versions](https://docs.kentico.com/13/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:

1. Open the **Pages** application and select a page which you want to compare in the content tree.
2. Click the **Compare** button below the content tree.

![The compare button.](https://docs.kentico.com/docsassets/13/comparing-language-versions/compare_button.png "The compare button.")

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.

> **Note:** The comparison mode is primarily targeted for editing pages on the **Content** tab. It is also supported for page **Properties,** except for the properties shared by all language versions (e.g. _Linked pages_, _Related pages_, _Security_ or _Language_ tabs).
>
> The language version comparison mode is currently **not** supported on the **Page** tab of the Edit mode and in the **Preview** mode.

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

| **B. Vertical layout**        | Splits the editing area vertically.                                                                                                                                               |
| **C. Horizontal layout**      | Splits the editing area horizontally.                                                                                                                                             |
| **D. Synchronize scrollbars** | If selected, scrollbars in both parts of the editing area are synchronized, resulting in the same sections of both language versions being displayed while scrolling.             |
| **E. Language selector**      | You can choose which language version of the page is compared with the selected language.                                                                                         |

> **Info:** \*\*Note:\*\*If you select a page whose version in the comparison language is not created yet, the standard **New culture version** dialog appears.
