        Themes

        The appearance of the SDK can be customized by setting the theme property. This requires a UiTheme configurable object.

        const myTheme = new Storyteller.UiTheme();
Storyteller.sharedInstance.theme = myTheme;

        This object is used as the global theme for every StorytellerListView included in your site.

        It is also possible to apply a specific theme to a specific StorytellerListView instance. For example:

        const storytellerRowView = new Storyteller.RowView("storyteller-row-view");
const myRowTheme = new Storyteller.UiTheme();
storytellerRowView.theme = myRowTheme;

        For more information on setting a theme on an individual list, see StorytellerListView.

        Configuring a UiTheme

        A UiTheme consists of the following properties:

        • light sets the Theme to apply for light mode
        • dark sets the Theme to apply for dark mode

        Which property is used depends on the uiStyle property of the StorytellerListView.

        Creating Themes

        The Theme object contains all of the properties which can be customized in the SDK.

        Some properties take their default value from others. For example, setting the primaryColor to #FF0000 will also result in the New Indicator for Rectangular Tiles being colored red. Such properties are indicated in the table below.

        Note that theme properties may be used for other situations in future.
