auto resize text (font size) when resizing window?

Question

Hi, I have been trying(in vain) to build a page whose elements would resize as I changed the window size. I have it working in css for images no problem, but I can't seem to accomplish the same for text, and I am not sure it is even possible in CSS. And I can't seem to find a jquery script that accomplishes this.

When a user resizes the window, I essentially want the page to scale dynamically and fluidly, without the user having to invoke page zoom. This works fine on my img divs via css, but not for the text, which stays the same size.

any ideas?

Thanks!

I've had to do this myself. What I did was that I set a base text size for the body, and percentages for all other sizes. I then used a simple jQuery script to change the base size on window resize. The other sizes then update as well.

I used something like this:

$(function() {
    $(window).bind('resize', function()
    {
        resizeMe();
        }).trigger('resize');
    });

and in the resizeMe-function, I had this:

//Standard height, for which the body font size is correct
var preferredHeight = 768;  

var displayHeight = $(window).height();
var percentage = displayHeight / preferredHeight;
var newFontSize = Math.floor(fontsize * percentage) - 1;
$("body").css("font-size", newFontSize);

You can do this with CSS3 media queries, specifying different base font-sizes depending on browser size. There is a good article for this on A List Apart

For IE support you might be able to hack it using CSS expressions

This requires you to use a fixed base font-size, for instance on the body tag, and percentage or em based sizes elsewhere.
