# Themes

### General

Qlik Sense datasources support themes which can be used to define the style of visualizations and sheets within an app. To activate a particular theme in Mail & Deploy you can use an [Activate Datasource Theme Action](/version340/docs/activate-datasource-theme) or by setting the Default Theme property of the datasource.

### Theme Identification

When activating a theme using the Default Theme property of the datasource or an [Activate Datasource Theme Action](/version340/docs/activate-datasource-theme), you need to provide the identification of the theme to be activated. To find the identification of a theme in Qlik Sense Server (on-prem), you have to open the app in the hub and navigate to any visualization, then right click the visualization, click Share and then Embed. The following dialog will show up:

In the *Theme* field you can then select the theme whose identifcation you are looking for; when you have done that, the theme identification will be added to the *Iframe to embed in your web page* field at the bottom of the dialog.
