Is there a method to adjust the height of an iframe in the y-axis so that the content properly fits within it?
The challenge lies in finding solutions that work within the constraints imposed by modern CORS and Same Origin policies enforced by web browsers.
Despite these limitations, platforms like eBay seem to have found a way to resize iframes based on their content's height. Initially, I suspected this functionality might be server-side, but upon disabling JavaScript, I noticed that the iframe's starting height is approximately 10k px.
What specific attribute of the child-frame allows for this seamless resizing that can be accessed by the parent frame?
