min-max-font-size

Using vw or vh CSS units for font-size? Set a min or max font-size for your type.

Setup

Add mm-fontsize.js at the end of your HTML page, just before the closing body tag.

	…
	
	<script src="./path-to-js/mm-fontsize.js" type="text/javascript"></script>
		
</body>
</html>

Now you can start manually adjusting kerning in your own CSS.

CSS Syntax

To use the min-font-size or max-font-size propery, just write it in your CSS like any other property:

h1 {
	font-size: 4vw
	max-font-size: 50px;
	min-font-size: 20px;
} 

Notes:

• This is only for when using vw or vh units for font size.
• Right now, px is the only unit accepted for min and max-font-size. (Working on ems.)

This script is a Stylefill

A ‘Stylefill’ is a way to create new CSS properties using JavaScript. Stylefills are similar in concept to a polyfill, but are only focussed on extending CSS in new ways, and Stylefill.js is a library to help make it much easier.

Support

mm-fontsize.js will work in any browser that accepts vw or vh CSS units.
