For example, when i use an iframe, example
<iframe src="somesite">your browser doesnt support iframes</iframe>
ok, but the source (somesite) has your own width and height and how to update on the client (the page that will show the iframe content) the exact size of the source (somesite in this case)?
index.html will host the iframe content
content.html is the iframe content
index.html should show in an iframe, the content.html but with it exactly size... no matter the width or height of the content, index.html will adjust it...
