Can someone shed some light on the rationale and usefulness of the inline "iframe" and "srcdoc" attributes? I read the description, I understand how they work, but I'm not sure what they are good for.
Mike West, developer advocate at Google Chrome in Münich, had a great talk, recently at GOTO Aarhus, where this was mention.
The talk was focused on security and mentions the new sandboxed iframes[1]. With the inline iframe, iframe's can now be used as div – a sandboxed div.
The idea is that you can sandbox e.g. social buttons by putting them in a sandboxed iframe. You can also populate the iframe's without extra HTTP-requests by the iframe, by using "srcdoc". This is a perfect way to sandbox user generated comments on your blog.
