HubSpot Form Styling Beyond the Builder’s Options

[CSeevinck]

I have an embedded HubSpot form and need to make some style adjustments that aren’t possible through the form builder’s built-in options. I’d like to keep HubSpot’s default styles but add my own CSS on top.

I’ve read that it may be possible to inject custom CSS into the form’s iframe using JavaScript. Can anyone confirm if this is supported and point me toward the best approach or documentation for doing it?

Hi @CSeevinck,

Are you referring to the new form builder? If so: Accounts Dashboard | HubSpot

After publishing your form (orange ‘Review and update’ button in the top right corner), you should see this. Follow the numbers to get the embed code:
