Thank you very much for your continued help.
I tried the CSS solution, but I couldn't get it to work. I think this might be because the iFrame is getting it's own CSS. (Just an hunch, I'm completly open for correction)
I tried creating an on load event but it doesn't seem to be working either. I hate to keep bothering you but I would appreciate any thoughts on why it still isn't working. Thank you!
<!-- box-container -->
<iframe width="760" height="1231" frameborder="0" src="https://*****" marginheight="0" marginwidth="0" onload="load()">Loading... </iframe>
var ele = document.getElementsByClassName('ss-footer');
ele.style.display = "none";
