Not able to change the css of the form

Hi @ankitasar, you can create, edit, and launch HubSpot forms for free in the plugin. And under Settings / Forms / Styles, you can change global styling preferences for all forms across your website.

But certain styling options for individual forms and CSS options are only available in Marketing Hub Starter or above. Here are two knowledge base articles with more information on HubSpot forms:
