No, No, and NO! iFrame is an accessibility /FAIL/ since the user cannot see the actual URL to what's being displayed, wastes bandwidth for stuff you should probably be inlining, and opens the door to XSS exploits if the content of the iframe is off-site (like adverts). To top it off, it's deprecated in STRICT doctypes, and you SHOULD be writing in STRICT. Tranny is for supporting old, outdated half-assed bullshit code by people who haven't updated their skills in the past decade; NOT for writing new code.
