Hello Jeff,
I've been battling with trying to get forms 2.0 to work with my responsive landing page and stumbled upon this thread. In your latest post you said that using forms 2.0 with embed capabilities makes integration much easier. I've always opted to embed my forms instead of dragging them onto our Marketo landing pages to ensure that I have 100% control of where the form goes. I'm attempting to keep my methods the same and just use jQuery to strip all of the marketo form classes / styles and replace them with my own so that the form behaves 100% responsively with my page and looks the way I'd like it to without having to go through all of the trouble of adding !important to all the styles I want in the form CSS editor.
Are you still using your clone method to get the forms to be behave as responsively as possible or has the forms 2.0 API documentation lead you to a better approach?
