Lightweight jQuery extension for dynamically changing font sizes according to container / browser width.
Intended for use with responsive or adaptive CSS layouts.
Include the latest version of jQuery and jQuery.fontFlex.js in the <head> of your HTML document:
<script src="jQuery.min.js"></script>
<script src="jQuery.fontFlex.js"></script>Define a default CSS font base by setting font-size: 1em and line-height: 150% on the body or intended element. Declaring the font-size is optional, but highly recommended in case javascript is disabled. Finally, call the plugin on said element. Live Demo: code.nath.co/fontFlex
Syntax Example
$(function() {
// All elements
$('body').fontFlex(14, 20, 70);
// H1 only
$('h1').fontFlex(24, 36, 70);
});Custom Parameters

max Maximum font-size in pixels
mid Mid-range buffer. Values ranging from 60 to 70 produce the best results. Lower values produce a larger initial font-size, while higher values produce the opposite. Adjust accordingly to fit your requirements.
