title: Any disadvantages to using iframes
body: <p>I've been <a href="https://stackoverflow.com/questions/3889868/how-to-share-a-form-between-2-websites">advised to use an iframe</a> to share a form between 2 websites, but I always got the impression that iframes are bad or that they shouldn't be used. Not sure I even remember what gave me this impression. So can someone clarify if using an iframe is bad practice or not, and if it is bad practice, why?</p>
