  • Automatically remove unused CSS rules
  • Time: 2:30pm - 3:20pm | Room: Bayview A

As more and more people start using CSS libraries like Bootstrap, our CSS files are full of unused rules. Not only they take away unnecessary bandwidth (which matters a lot on mobile), they also slow down the browser since it has to parse all the rules and test to see if they apply to the current page.

Through this talk, I'll show how you can use node-uncss and grunt-uncss to automate the process of removing CSS rules that are not used in your pages.
