<p>I want to embed iframes to any random website, without the visitors noticing that it's actually a different frame. I want the iframe to merge with the parent body, extending the body of the parent, so that the non-iframe-part and the iframe-part of the website can be scrolled only using the main scrollbar of the parent page.</p>

<p>This is my code so far:</p>

<pre><code><h1>Tours</h1>

<div style="background-color: red; color: white; padding: 200px; text-align: center;">
 Top part of page
</div>

<iframe id="tourtask-iframe" style="overflow: hidden;" src="/public/index.php?b=eit&token=abcd1234&p=tours&lang=en">Please upgrade to a browser that supports iframes.</iframe>

<style>
body, html {
 width: 100%;
 height: 100%;
 margin: 0;
}

#tourtask-iframe {
 width: 100%;
 height: 2000px;
 border: none;
}
</style>
</code></pre>

<p>When I do a <code>overflow: hidden;</code> on the body of the source file of the <code>iframe</code> archive, the scrollbar disappears, but I'm unable to scroll the iframe portion of the page.</p>

<p>I'd need to update the height of the <code>iframe</code> element to fill up the 100% of the height of this file. I'd also need to update the height of the <code>iframe</code> element whenever I expand/collapse any collapsible content in the frame. </p>

<p>How can this be done? Or is there a better way? </p>

<p>I'd preferably not use any library/framework for the parent page, since I'll need to be able to embed this iframe to totally different webpages.</p>

<p>Thank you!</p>
