Text-balancer is a javascript module that seeks to eliminate typographic widows from text. It does this by setting the max-width of the dom node to the threshold that it would spill onto another line.
Install it into your project via npm
npm install text-balancer --save
https://www.npmjs.com/package/text-balancer
We use bramstein's Font Face Observer to check when our fonts have loaded: https://github.com/bramstein/fontfaceobserver
We run our text-balancer once our fonts load.
import textBalancer from 'text-balancer';
// Run it when you want to with any set of selectors
textBalancer.balanceText('.headline, .interactive-leadin, #horse-god');
// OR: Just run it and it will look for anything with the balance-text class
textBalancer.balanceText();
No tests right now, but we're working on them! It's being used on nytimes.com and has been debugged and tested extensively on that.
