general question: using pinch gesture to scale div/class.

[nosarious]

This is just a general question but would anyone know how I could go about setting up a pinch event on a particular div in my layout that would allow me to use the css zoom function? Most of my layouts are set to 240 px wide for the columns, but rather than going through the process of changing the fonts (several svg fonts are used), I thought it would be easier to just use the css zoom on the entire div.

Is this even possible? Anyone able to help me do this?

My other alternative is to have a preferences menu that lets people pick a font size, but that gets less intuitive, especially since zooming is usually done with pinch (but I don't want the entire page to zoom, just the div with text in it)

Thanks to whomever can help with this in advance.
