IFRAME SEAMLESS="YES" and printable consolidated m

[urbanjost]

Many sites (including forms.whatwg.org) maintain manuals in three formats -
multi-page for on-line viewing
consolidated single-page copy for scanning
consolidated single-page copy for printing
I have had less than fully satisfying results using IFRAME and JavaScript
to allow maintaining a merged printable document with just the browser
interface. I have been assuming SEAMLESS="YES" would allow my to
use just IFRAME elements to do this easily, but I see very little discussion
about it and find no browser implementing it. The HTML5 spec doesn't
directly address things like spelling checks and "find" searches; but seems
to imply I can make a printable document. Assuming I want to do what
I discuss at

http://home.comcast.net/~urbanjost/MERGE/PRINTME.html

(seamlessy merge a list of documents into a printable document) can I be
assured that is what this attribute will provide if implemented?

Spelling checks and inline searches is a browser UI feature and not part of HTML5. HTML5 does define that the <iframe> height/width need to be stretched to fit the content. Also, it allows you to style the loaded page from the document the <iframe> is in.

No browser has implemented or started implementing this feature.
