In the 2-frame 'rows=' frameset I have, if a user change of the zoom level to less than the 125% value that I coded for, they will see "dead space" between the frames.

This question: How to detect page zoom level in all modern browsers? shows how to detect the browser's zoom level.

Is it possible to adjust the browser's zoom level using Javascript so I can keep users from changing the zoom outside of the desired levels?

Or have I simply forgotten a default coding consideration of some kind? (I've seen CSS's 'zoom' style, where presumably default zoom levels can be set.)

I am also seeing document.body.style.zoom, so seems we could do something like:

if (zoomLevelChange)
  {document.body.style.zoom= [some calculation]; }

  • Is it really possible =nobody else= has seen this? Does no one else use a 2-frame rows frameset? I know frameset use is frowned upon, but there is no way else to keep a top banner stationary, while changing out the bottom frame. A scrolling
    allows the former, but not the latter. -sk

    AJAX is a more modern way that can do that. – Jimbo Jonny Aug 02 '12 at 20:37
