Resizing iframe? - Webkit or Firefox

is it possible the proportions within an iframe? e.g. 100%, 50%, 25%, ...

I would like to implement a "magnifying glass" for a webpage or iframe. It does not have to be implemented in Javascript within a website, but even a desktop solution would be great.

Is this a possibility? or would it be incredibly complicat开发者_StackOverflow中文版ed?

Any ideas? Help would be amazing =)

In Firefox you can use the -moz-transform CSS property to zoom, using the scale() value. Note that this doesn't change the amount of space that the element takes up on the page.
