# Customizing the look of the Web Portal

The Web Portal pages presented to the users are generated dynamically based on configuration files.

The following aspects of the presentation can be adjusted:

- If you are using Domains, the icon in the Web Portal is sourced from the icon defined for the Domain in the Management Client.
- You can add new languages.

It is possible to customize the Web Portal source files more extensively, but with some major limitations:

- Any changes to files are overwritten at upgrade.
- It might not be possible to reuse customized files after an upgrade. You might have to customize the corresponding new files after the upgrade.
- Customization requires knowledge of HTML and CSS coding.

With these issues in mind, the following local files on the Web Portal Server control how content is shown to users, and are fairly safe to edit:

- The CSS files are stored in <installation directory>/webserver/webapps/webclient/resources/css/.
- The page template files that are stored in <installation directory>/webserver/webapps/webclient/ as several .jsp files.
- The help pages that are stored in <installation directory>/webserver/webapps/webclient/help/ as several .jsp files.

Note: We recommend that you create backups of the files before you edit them.
