# FitText.js, a jQuery plugin for inflating web type
FitText makes font-sizes flexible. Use this plugin on your fluid or responsive layout to achieve scalable headlines that fill the width of a parent element.

## How it works
If you're working on a responsive design, take whatever headline you'd like to scale and set the item to FitText. Oh. and you'll want to include jQuery n' all that too.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
<script src="jquery.fittext.js"></script>
<script>
$("#responsive_headline").fitText();
</script>

[Pretty Cool](http://www.hulu.com/watch/194733/saturday-night-live-miley-cyrus-show). Your text will now resize based on the width of the item. (by default: ~1/10th of the element's width).

### The Compressor
The default setting works pretty well, but when it doesn't FitText has one setting you can adjust. If your text resizes poorly or is resizing all hurdy gurdy, you'll want to turn tweak up/down the compressor. It works a little like a guitar amp.

$("#responsive_headline").fitText(1.2); // turn the compressor up (font will shrink a bit more aggressively)
$("#responsive_headline").fitText(0.8); // turn the compressor down (font will shrink less aggressively)

This will hopefully give you a level of "control" that might not be pixel perfect, but scales smoothly & nicely.

## CSS Tips

* Set your target headline to `width: 100%` in your CSS. And if you set a font-size, this will act like a `max-font-size`.
* Be ready to tweak till everything balances out.
* So far, FitText seems to work with other fun properties like text-shadow
* It also works with [Lettering.js](http://github.com/davatron5000/Lettering.js)! #synergy

### Disclaimers & Forks
As always, use JavaScript with caution: plan for no-js fallbacks that you are comfortable with.

Also please Download, Fork, & Commit. We'd love your see your ideas.
