load-style
Syntax
load-style: "url" [every (time)] [after (time)][, (class)...];
url = The url of the CSS stylesheet file to load.
This example loads the font-awesome css after the page is active and Active CSS has started.

body:init {
load-style: "/font-awesome/css/all.css";
}
The stylesheet location is stored in memory as having been loaded and will not be retrieved from the server again if run more than once.
This technique is good for boosting page loading performance, but can have a detrimental effect on initial display due to the lag. It is not used on this site, as it just looks nicer without it.
