[OT] HTML: div/iframe hybrid?

[Adam D. Ruppe via Digitalmars-d]

I don't think it is a security hole, but websites typically do 
not get to set their viewport - the window size is under the 
user's control. (one of the few things they have left under the 
user's control!)

So if you told a site to set its own size... it wouldn't really 
know what that is most the time. At least widths tend to be fluid 
and variable. Heights sometimes are set dynamically too.

There's solutions to this - the containing page might set it to a 
width, then let the height be fluid. That's what most the JS 
solutions do and it works pretty well. But maybe that still feels 
too hacky for the standards committees, or is just messy to 
implement for the browser developers.
