I need to correct the iframe display to complete the payment information of a subscription.
It looks like this:
You can use the media querys to adjust the size of the item depending on the screen.
If you are using bootstrap I recommend that you take a look at the system Grid that it has. It is very easy to use and is Responsibe with virtually all devices.
Insists to give a fixed width and height depending on the size of the screen, or the iframe
or the div
container of this.
