How can I position a button on a product page using CSS Smart Selector?

[Helen_Wild]

Hi,

We own an app in Shopify that allows stores to inject a button in their product page. We are looking for a solution that enables the merchant to select on the screen the right position for the button.

See video here: https://www.loom.com/share/7bf6ea98942e4b2c8399b00a94a047c9

Why do we want to do this?

It is extremely challenging for us to find a single CSS class that is common across majority of the themes and that we could use as default.

Any help or hints would be highly appreciated!

Kind regards
