Is it possible to change the appearance of the VK widget "Subscribe to the author"?

Question

css

Hello, I'm interested in the question of the ability to get to the styles inside the frame generated by the widget.
I tried this: I get an error: Blocked a frame with origin " domain.com " from accessing a cross-origin frame.
$('#vk-subscribe').find('iframe').contents()

No, but you can set the vk widget to zero transparency and place it on top of your own button.
