How can I customize the widget?

You should be able to customize the colors by going to: Seal Subscriptions > Settings > Subscription widget.

If you wish to style the widget further, you should be able to achieve this with some CSS code. You can edit the CSS code by going to: Seal Subscriptions > Settings > Custom settings > Advanced > Custom CSS.

If you don't know CSS, we advise you to contact the store developer or hire a Shopify Partner (https://www.shopify.com/partners/directory/services).

If the customization is simple enough, you can let us know and we will try to help you.
