Use global styles in PHP

I’m loving the global styles feature of GB Pro. Awesome work!

I’m wondering if it’s possible to “pull” a global style in PHP. I’m sometimes creating my own stuff (e.g. a certain element with dynamic data as a shortcode), which should then contain e.g. a button (which I have designed as a global style in GB).

Do you have any advice?

Thanks a lot in advance,
Marc
