Automatically Adjusting iFrame Height (CSS)

Question

Automatically Adjusting iFrame Height (CSS)

I am facing an issue with my iframe. I really want the iframe to automatically adjust its height based on the content within it. My preference is to achieve this through CSS without relying on javascript, although I am open to using javascript if necessary.

I have experimented with CSS properties like height: 100%; and height: auto;, but so far, I haven't found a solution that works!

Here's the CSS code for the frame...

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

And here's the CSS for the page inside the frame...

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

The code of the page 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 take note that the URL in the iframe is different from the host website. However, I have access to both websites.

Could anyone provide assistance?

html css iframe height

Answer №1

Dealing with a similar problem, I discovered an effective solution:

To ensure a responsive YouTube embed, utilize padding and a container element to establish a fixed aspect ratio. This technique can also be applied to other iframe-based embeds like slideshows.

Consider the typical YouTube embed code with fixed dimensions:

<iframe width="560" height="315" src="//www.youtube.com/embed/yCOY82UdFrw" 
frameborder="0" allowfullscreen></iframe>

Although it may seem convenient to set a 100% width, this approach won't adjust the height. Instead, encapsulate it within a container with specific class names and without setting width and height attributes:

<div class="container">
<iframe src="//www.youtube.com/embed/yCOY82UdFrw" 
frameborder="0" allowfullscreen class="video"></iframe>
</div>

Apply the following CSS rules:

.container {
    position: relative;
    width: 100%;
    height: 0;
    padding-bottom: 56.25%;
}
.video {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

For further details, refer to the source where I found this solution:

Depending on your specific aspect ratio, adjustments might be necessary for the padding-bottom: 56.25%; to achieve the desired height.

Here is a simple solution using only CSS!

To enable scrolling in your iframe, just add 'scrolling yes' to the code:

<iframe src="your iframe link" width="100%" scrolling="yes" frameborder="0"></iframe>

And here's the trick:

<style>
    html, body, iframe { height: 100%; }
    html { overflow: hidden; }
</style>

No need to worry about responsiveness with this method :)

You can resolve this issue by adding the following code snippet to your HTML section:
<script>
  function adjustFrameSize(obj) {
    obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
  }
</script>
Make sure to update your iframe tag as follows:
<iframe src="..." frameborder="0" scrolling="no" onload="adjustFrameSize(this)" />

This approach involves using javascript, but it offers a simple and effective way to address your resizing problem.

Answer №6

It's important to understand that the div tag essentially acts as a container for content without affecting its layout. This means that if you insert a lengthy paragraph with 100 lines of text inside a div tag, the height of the div won't automatically adjust to accommodate all the text.

To address this issue, you can implement a simple CSS and HTML workaround. One solution is to utilize an empty div tag with the class "clear", which can then be styled using your CSS. Additionally, make sure that there is a reference to #wrap in your CSS file even though no such ID is currently present in your code. In essence, your revised code should resemble something similar to the following:

HTML Code:

    <!-- Change "id" from "container" to "wrap" -->
    <div id="wrap">
        <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>

            <!-- Add this line -->
            <div class="clear"></div>
        </div>
        <div id="footer">
        </div>

        <!-- Add this line -->
        <div class="clear"></div>
    </div>

Furthermore, include the following code snippet in your CSS file:

.clear{ display: block; clear: both;}
