Hi, how to overwrite the css on my form?, I followed the tutorials but not working, this is my code ```auto Test ``` I follow [this article](https://knowledge.hubspot.com/articles/kcs_article/forms/how-do-i-remove-the-default-styling-from-hubspot-forms) but not showing the checkbox _Include default styling._ I’m doing something wrong? ---

I checked the forms on my portal. When you go to contacts → forms in your Hubspot portal, then click ‘action’ next to a form and choose ‘embed form’ a popup appears with the embed code. below the code is the check box. are you using embeds on an external site or a hubspot hosted site? ---

Indeed go to the form \> actions \> embed code and add the lines from the example as well if they are not there: ```auto ``` Portal and form Id are already filled in. SubmitButtonClass: add the class of the button css: ‘’ makes sure that the default css is disabled cssClass: add 1 class (2 won’t work is my experience, but if you succeed please let me know). ---

I am having issue that it’s show “[]Unsupported context key: className” I am passing down className as a prop into `cssClass` as there are a few forms sharing the same script with different styling and form Id Do you know what may cause the issue? Thank you.
