Reduce the size of the above-the-fold content | PageSpeed Insights | Google Developers
Dino Dogan stashed this in Web Dev Resources
Why would we want to reduce the size of above the fold content??
I haven't had a chance to go through the whole document in detail so take this with a grain of salt. The idea is to enable the most important part of the page to load first and fast. It's how youtube does it. When you land on a new video the video will often start to play before the rest of the page loads.
I'm researching best practices. This seems to be one of them. You're an experienced CSSer. What do you think?
I agree. Load the page asynchronously starting with the most important part first.
Speed is the most important feature of a website.
