[javascript] Scale the contents of a div by a percentage?

Building a CMS of sorts where the user can move around boxes to build a page layout (basic idea anyway).

I'd like to pull the actual contents in from the database and build out the "page", but have it display at 50% scale.

I realize I could have 2 sets of CSS - one for the actual front-facing page, and one for the admin tool and just shrink everything accordingly, but that seems like a pain to maintain.

I was hoping there might be some kind of jquery or CSS or something that would allow me to populate a div and give it the properties (?) of 50% scale.

This cross-browser lib seems safer - just zoom and moz-transform won't cover as many browsers as jquery.transform2d's scale().

For example

$('#div').css({ transform: 'scale(.5)' });

Update

OK - I see people are voting this down without an explanation. The other answer here won't work in old Safari (people running Tiger), and it won't work consistently in some older browsers - that is, it does scale things but it does so in a way that's either very pixellated or shifts the position of the element in a way that doesn't match other browsers.

Or just look at this question, which this one is likely just a dupe of:
