Qlik Sense comes with four default themes (Sense Classic, Sense Focus, Sense Breeze, and Qlik Horizon) and in addition to these you can create custom themes based on your company standards.
With custom themes you can precisely style an app by changing the colors, adding images and backgrounds as well as specifying the font sizes and font colors on a global or granular basis throughout your app. You can also define color palettes to be used and customize the specifications for margins, padding and spacing.
A custom theme is a collection of files stored in a folder. It must contain a definition (QEXT) file, a main JSON file, and optionally any other assets you might need to support the custom theme, such as CSS files, custom font files and images.
The custom styles are defined in the following way:
- In the JSON file you define the style for the individual visualization types, for example bar charts and line charts.
When you have created a custom theme, you store it in Qlik Sense as an extension. The JSON file and any additional resources are zipped and imported as an extension in the Qlik Management Console (QMC). This enables that security rules can be added in the QMC for controlling which themes specific users have access to.
