How to get only the most needed css for faster loading?

[RoxBrock]

I have been using the Firefox duster app to clean up my css so only the page rendering css is loaded when my page is loaded. But it doesn't seem to be working now. Does anyone know of another tool that will do this for me?

This seems like something that's a little beyond the scale of an app. SitePoint did a great breakdown of the whole ecosystem of page rending here: http://www.sitepoint.com/optimizing-critical-rendering-path/ that details the steps to go through regarding loading pages as quickly as possible. That said, a CDN like Cloudflare would be better suited to the task: https://www.cloudflare.com/features-optimizer. Cheers!
