jQuery text resize issue

I am attempting to loop through some span's of text and resize the text to fit within its containing div based on the smallest font size required to do so.

<div id="preview">        
        <div id="test">
            <section class="slide">
                <span>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<br />
                Nam in mauris a magna elementum ornare vel at velit.<br />
                Nulla facilisi.<br />
                Sed eu odio id urna fermentum imperdiet eget sit amet enim.</span>
            </section>

            <section class="slide">
                <span>Cras cursus ante et tortor placerat sodales.<br />
                Curabitur libero quam, cursus sit amet feugiat id, elementum at lectus.<br />
                Integer volutpat aliquet massa at adipiscing.<br />
                Vivamus purus leo</span>
            </section>
         </div><!--/ #test -->
    </div><!--/ #preview -->

My jquery I have to do this so far is

var fontSizeArray = [];

$('#test > .slide').children('span').each(function () {
    var currentFontSize = parseInt($(this).css('font-size'));
    do {
        currentFontSize = currentFontSize + 1;
        $(this).css('font-size', currentFontSize);            
    } while ($(this).width() < $('#test').width());
    fontSizeArray.push(currentFontSize);
});

var smallest = Math.min.apply( null, fontSizeArray );      

$('#test > .slide').children('span').each(function () {
    $(this).css('font-size', smallest);
});​

I have created a fiddle to better illustrate this.

Basically all of the text should be resized to fit within the div #test

Add a conditional after the loop that checks if you've gone too far:

if ($(this).width() > $("#test").width()) {
   currentFontSize--;
}
