How does shopify/impulse determine [data-button_style=angled] in css?

My store is using the impulse theme. I am not a fan of the angled buttons that it uses.

Looking through the CSS in inspector, it’s pulling in “[data-button_style=angled]” in the buttons.css which I can’t seem to find where this is generated in the code(button.css doesn’t exist)s

Thanks!

Where do you see button.css can you share the store url and a screenshot.

It’s at the lower end of the page for the newsletter subscribe button

I’ve gone about it by fixing this particular button by using:

.btn:before {
  transform: none !important;
}
.btn:after {
  transform: none !important;
}
