FitText.js, a jQuery plugin for inflating web type

FitText makes font-sizes flexible. Use this plugin on your responsive design for ratio-based resizing of your headlines.

How it works

Here is a simple FitText setup:

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

Your text should now fluidly resize, by default: Font-size = 1/10th of the element's width.

The Compressor

If your text is resizing poorly, you'll want to turn tweak up/down "The Compressor". It works a little like a guitar amp. The default is 1.

jQuery("#responsive_headline").fitText(1.2); // Turn the compressor up   (resizes more aggressively)
jQuery("#responsive_headline").fitText(0.8); // Turn the compressor down (resizes less aggressively)

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

minFontSize & maxFontSize

FitText now allows you to specify two optional pixel values: minFontSize and maxFontSize. Great for situations when you want to preserve hierarchy. You can specify two optional values for the LineHeight: minLineHeight and minLineHeight and last parameter is default false, it measure by html element, when you set it on true, then would be measure from browser window

jQuery("#responsive_headline").fitText(1.2, { minFontSize: '20', maxFontSize: '40' })
jQuery("#responsive_headline").fitText(1.2, { minFontSize: '20', maxFontSize: '40', minLineHeight: '20', minLineHeight: '32', windowSize: true })

CSS FAQ

• Make sure your container has a width!
  • display: inline elements don't have a width. Use display: block OR display: inline-block+ a specified width (i.e. width: 100%).
  • position:absolute elements need a specified width as well.
• Tweak until you like it.
• Set a No-JS fallback font-size in your CSS.

Don't use jQuery?
