Recompute the font size of an element based on its width. 
%ENDSECTION{"summary"}%

---++ Usage

---+++ !JavaScript API
The =fluidfont()= plugin attaches to a jQuery object and recomputes its font-size based on its width.
You can specify a width at which the original font size should be used. When the element is resized
the ratio between width and font-size is maintained continuously.

*Parameters*:

   * width: standard width that will show the original font-size 
   * min: minimal font size in px 
   * max: maximal font size in px

---+++ Foswiki integration
!FluidFont is activated for any html element that has got the ==jqFluidFont== class. Options can be specified
using JQueryMetadata.

---++ Examples
%JQREQUIRE{"fluidfont"}%

<div class="jqFluidFont {width:960, min:7, max:20}" style="border:1px solid #ddd;padding:10px">
