You’d need to make the style changes in wherever the iFrame content is coming from. e.g. procheck24 etc.

Hello…thanks for feedback - so, if I cannot get there, is it impossible to change the look?

Not really - the iframe just brings content from elsewhere and the styling you are talking about is controlled from the stylesheet in the original form

oh, thats sad…but thanks for getting beck! I thought, I could write something in CSS that says: "Hey, look at the iframe xxx…please take it and make the inside look like the rest :slight_smile: " …
