Theme JSON Support

All the CSS variables can also be defined directly inside your theme’s theme.json under the settings.custom key.

For example:

{
  "settings": {
    "custom": {
      "carousel-block": {
        "navigation-size": "22px",
        "navigation-color": "#000",
        "pagination-bullet-active-color": "#000"
      }
    }
  }
}

Frontend API

Carousel Slider exposes a small frontend API for integrations with tabs, accordions, modals, or other hidden UI.

For some of these dynamic layout cases, the Advanced Settings observer options can also handle updates automatically.

• window.CarouselSliderBlock.init( container ): Initializes carousel instances inside the given container.
• window.CarouselSliderBlock.update( container ): Updates existing carousel instances inside the given container and initializes any that are not yet initialized.
