</div>I don't understand the question. How does the viewport affect the bounding<br>

I just thought of another problem with allowing the contents of a<br>
"seamless" iframe to overflow outside the iframe box.<br>
<br>
One of the main uses for this will be to sandbox blog comments, using the<br>
yet-to-be-defined doc="" attribute, as in:<br>
<br>
<iframe doc="<!DOCTYPE HTML><p>You suck"<br>
seamless sandbox="allow-same-origin"></iframe><br>
<br>
If we allow the contents to flow out of the box, then we also allow blog<br>
comments to start overlapping other content on the page.</blockquote></div><div><br>Yeah, although setting overflow:hidden on the iframe could be used to prevent that.<br><br></div><div class="Ih2E3d"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

</div>The way forum pages work now is that the content ends up screwing up the<br>
rest of the page, so I think that's a good thing. :-) People work around<br>
this now by forcing line break opportunities to exist in long URLs, etc,<br>
or by setting overflow:auto on user-submitted content.</blockquote></div><div><br>Yes, although it would be nice to offer authors a choice. Oh well, I suppose it doesn't matter too much.<br><br></div>Rob<br></div><div class="Ih2E3d">
