Hi,
you can maybe use javascript that will be apply after the page creation.
You can use jquery to find more easily the iframe element specialy that you probably doesn't know the complete id...
var iframe = document.getElementById('h5p-iframe-862');
var style = document.createElement('style');
style.textContent =
'body {' +
' border: 10px solid red;' +
'}'
;
iframe.contentDocument.head.appendChild(style);
It's inspired by the code from there : https://ask.xiaolee.net/questions/1065204
Hope it's help.
