Embed codes without JavaScript

The squarespace code includes javascript which squarespace only uses in it's business plan now. How can you embed the code with only css?

Unfortunately, you cannot embed a form using only CSS. There must be HTML codes at least.

And yes, the embed codes provided have Javascripts in them, but you can ditch it and just use the iframe embed part:

It only uses plain HTML and inline CSS codes.

It also says it doesn't support iframe? Is there any other way?

Unfortunately, we cannot embed the form using only CSS - so I guess upgrading to a SquareSpace premium plan is necessary for you to embed the form using the code provided (mentioned in the guide).

Or you can just create a hyperlink to the form using this html code below:

<a href="YOUR FORM URL" target="_blank">CLICK HERE TO OPEN FORM</a>

However, this will take the user outside your webpage and open the form on a separate tab.
