Slides: Advanced CSS Performance Tooling


These are the slides from my CSS performance tooling talk, presented at CSSConf.eu earlier this month.

High-performance sites need to feel instant and deliver the goods in < 1000ms. In this talk, learn about the bleeding edge tools that can automate keeping your CSS on the fast path. Automate generating critical-path CSS, removing unused CSS, discovering duplicate selectors, colors and more.
