Hi,

Please, look at https://www.htmlelements.com/docs/window-css/. Scroll to the bottom of the page, where we have an example. I will also copy it here to show you how to apply CSS variables

<style>
        #window{
            --smart-window-header-background: #547284;
            --smart-window-background: #f5fafd;
            --smart-window-header-color: #f5fafd;
        }
</style>

Best regards,
