I have an iframe that loads my own payment form, when it is sent the response from the endpoint are some buttons with the payment methods, the problem is that it occupies less than the height of the iframe and it generated a white background in the space that surplus. The code would look like this:
<iframe id="myIframe" title="Form" src="index2.php"style="max-width:570px;border-style:none;min-height:100px;height:750px;" allowtransparency="true"></iframe>
With the chrome inspector mode I entered the iframe code and manually entered allowtransparency="true" when the payment methods are already loaded and the background is removed, the problem is that this does not work when you put it from the code, the new content loaded ignores this attribute.
Any way to force transparent background? Thank you
