I have a website that I want to nest an external Google Blogger Blog in an Iframe on a .cfm container page. Have tried many solutions--no cross domain security warning but iframe just does not resize.

Please: EZ to follow instructions, I am 80% designer, 20% coder....

I do have access to website and html blogger code.

Many, many thanks!
CFM CONTAINER PAGE CODE:

 

<body>

<div id="maincontainer">

 

<div id="topsection">

<cfinclude template="header3_alt.cfm">

</div>

 

<div id="fullwidthcontentwrapper">

<div id="blogcontentcolumn">

		<img src="images/blog-title.jpg" width="1002" height="78" />

<!--<div class="aboutMainText"> -->				

        		 <div class="center"><!-- BLOG -->

        		   <iframe id="idTopFrame" src="http://www.alexchingas.blogspot.com" height="1000" width="1000" scrolling="auto" frameborder="0"></iframe>

        		   <p></p>

		</div>

      <!--</div> -->

</div>

</div>

</div>

 

<div id="footer">

	<cfinclude template="footer.cfm">

</div>

</body>

</html>

    your iframe tag uses a fixed size (height, width attribute), use this attributes like:

      < iframe src="...." width="99%" height="99%" ...>

    BTW, the value for those attributes must contain a measure like px or % (which is missing in your example)

    You are correct, the iframe cannot have a height assigned (this is in place for client viewing). I have removed it and the iframe window shrinks down to @200px high. The source doc height was clearly not being read and I tried many solutions available on the internet.

    iframe can have a height attribute for sure, it just need to have a valid value like 1000px or 99%

    Neither of those--a pixel value, nor a %--work as I need to detect and dynamically resize the iframe window height according to the content, which is an external document.

    I have attached the changed code (removed the height attribute) and if you go to the page http://www.alexchingas.com/blog-container.cfm you will see what i mean. The window has shrunk to be a few hundred pixels high and the source doc is much longer.

    How do I get this to work?
