I'm currently using the Sagepay inframe on a few sites.
The problem is that the inframe is not responsive and I would like to make it as responsive as possible considering it's in a iframe.
Is there a way to change the template or edit the template with my own CSS or html at all? I had heard it was a while ago but can't find anything about it now.
After speaking to Sagepay I found I could download the custom templates here: http://www.sagepay.co.uk/support/find-an-integration-document/server-inframe-integration-documents which you can then send to Sagepay.
