I am having problems with my iframe. I really want the frame to auto adjust heights according to the content within the iframe. I really want to do this via the CSS without javascript. However, I will use javascript if I have too.

I've tried height: 100%; and height: auto;, etc. I just don't know what else to try!

Here is my CSS. For the frame...

#frame {
  position: relative;
  overflow: hidden;
  width: 860px;
  height: 100%;
}

And then for the frame's page.

#wrap {
  float: left;
  position: absolute;
  overflow: hidden;
  width: 780px;
  height: 100%;
  text-align: justify;
  font-size: 16px;
  color: #6BA070;
  letter-spacing: 3px;
}

The page's coding looks like this...

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" ��         "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" > 

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>...</title>
    <link rel="stylesheet" href="style.css" type="text/css" />
</head>

<body>
  <div id="container">    
    <div id="header">
    </div>

  <div id="navigation"> 
    <a href="/" class="navigation">home</a>
    <a href="about.php" class="navigation">about</a>
    <a href="fanlisting.php" class="navigation">fanlisting</a>
    <a href="reasons.php" class="navigation">100 reasons</a>
    <a href="letter.php" class="navigation">letter</a>
  </div>
  <div id="content" >
    <h1>Update Information</h1>
    <iframe name="frame" id="frame" src="http://website.org/update.php" allowtransparency="true" frameborder="0"></iframe>
  </div>
  <div id="footer">
  </div>
</div>
</body>
</html>

Please note that the URL within the iframe is different then the website the iframe will be displayed on. However, I have access to both websites.

Can anyone help?

Add this to your section:

<script>
  function resizeIframe(obj) {
    obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
  }
</script>

And change your iframe to this:

<iframe src="..." frameborder="0" scrolling="no" onload="resizeIframe(this)" />

It is posted Here

It does however use javascript, but it is simple and easy to use code that will fix your problem.

@SweetSpice, use position as absolute in place of relative. It will work

#frame{
overflow: hidden;
width: 860px;
height: 100%;
position: absolute;
}
