I am using embed form script for my php page. I need to use custom styling for my webpage. I have referred many docs and none of them works. I had tried to use "Set as raw html", but that option is locked for me. And also I tried with adding css: '', in my hubspot embed script. My subscription is below Marketing Hub Professional.
I need to use custom styling. Is there any way to achieve this?
It is by design that you're unable to add custom CSS when on a subscription below Professional. HubSpot forms are rendered in an iframe by default and the only means of adding custom CSS is to set it as a raw HTML form as you've mentioned.
This is a gated feature and we only allow the customisation on Professional or higher packages.
