#3222 closed enhancement (notabug)

Simple way to position dialog on resize

Instead of fixing the top and left position and hooking into window resize events there is a simple method to handle dialog positioning:

  • set top and left at 50%
  • set the margin-left and margin-top to the negative half width/height of the dialog

If you do this the browser itself will always position the dialog in the center of the screen. In addition this is simpler to style.

Resizing should not reposition the dialog. That would be completely unexpected behavior by the user. Also, the solution you provide only works for dialogs that are centered and haven't been moved at all by the user.

I disagree that this would be unexpected behavior. I believe that in most cases, this is the expected behavior. Point of fact, nearly all (if not all) lightbox/overlay scripts (not simple dialogs) work as reported by wichert (see above).

I understand that for a simple (modal) dialog this might not be the behavior the user might expect, but it is certainly the behavior when used as a lightbox/overlay.

Perhaps an option/flag allowing the user to decide the type of centering to be used (fixed/fluid) would be a valid enhancement.
