This is a long standing issue that's been bothering me for a while. It's only recently when I started getting into templates that I reliazed this more and more. I have taken a strong interest into performance websites, reducing the filesize and increasing the speed.
The way in which we write CSS affects the performance of the site, and indeed the Google Page Speed. I wanted to know what methods you all take into optimizing your site for speed, whether your host accepts GZIP or whether you're using a CDN. CSS in my understanding plays a lot of role into the way which your site is viewed and has an infleunce on any flash-of-unstyled content.
