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.
jQuery("#responsive_headline").fitText(1.2, { minFontSize: '20px', maxFontSize: '40px' });
CSS FAQ
- :warning: Run FitText before anything that hides the element you're trying to size (e.g. before Carousels, Scrollers, Accordions, Tabs, etc). Hiding an element's container removes its width. It can't resize without a width.
- :warning: Make sure your container has a width!
display: inlineelements don't have a width. Usedisplay: blockORdisplay: inline-block+ a specified width (i.e.width: 100%).position:absoluteelements need a specified width as well.
- Tweak until you like it.
- Set a No-JS fallback font-size in your CSS.
- :new: If your text is full width, you might want to NOT use FitText and just use CSS
vwunits instead. Supported in all major browsers.
