Setting IE "Optical Zoom" feature using Javascript/CSS

Question

The site I'm maintaining has been designed pretty rigidly using pixels for font sizes, dimensions, absolute positioning etc.

Now there is a feature request to add font resizing by users. While I know that is impossible without redesigning the site from the ground up using relative dimensions, I discovered that the site plays pretty nicely with the IE7/IE8 zoom feature (Ctrl + & Ctrl -).

The question is, is there a way to 'suggest' IE to open this site at a default zoom level (of say, 125%) without the users themselves requiring to zoom?

The site is used with IE 7+ only.

Answer 1

If this is your users Choice, leave it to their browsers most mature Browsers us a zoom that magnifies their page rendering (IE 7&8, Opera, FireFox, Chrome 2.0, Safari?). Besides depending on which system(screen resolution) your users are coming from will dictate their zoom choice. Unfortunately each browser handles remembering your zoom setting a little different for instance chrome remembers per site while ie is a global setting for each new tab/window.
