Is there any way to embed an external web page without using an iframe? I have access to both sites, I just want the page that the content is embedded on to resize based on
Question is good, but the answer is : it depends on that.
If the other webpage doesn't contain any form or text, for example you can use the CURL method to pickup the exact content and after then showing on your page. YOu can do it without using an iframe.
But, if the page what you want to embed contains for example a form it will not work correctly , because the form handling is on that site.
