Embedding website in iframe not working

Question

I am trying to embed the website www.zillow.com in iframe

<iframe src="http://www.zillow.com" style="width:33%;height:440px;" scrolling="yes" marginwidth="0" marginheight="0" frameborder="0"><p><b>Zillow</b></p></iframe>

But it does not return anything just blank, please advise

Answer 1

Yes i was able to embed other sites such as redfin and mris in iframe but not zillow.. They do block the iframe access. Anyway thanks for the guidance

Answer 2

I'm not an expert on the subject but my guess if they are blocking iframe access via .htaccess and/or javascript
