in this page it's said :
When your webpage loads, the browser takes certain steps that determine how the page will load (this is a simplified version, but basically what happens): Browser downloads HTML file It parses (looks through) the HTML It encounters something it must load (image, external CSS file, etc.) and stops parsing HTML It loads the external resource If external resource is CSS or Javascript it then parses that file It then continues to parse the HTML until it comes to another resource that must be loaded
So why alot people (and myself) were looking for a solution to capture load event on LINK and to detect When is a stylesheet really loaded as we can be sure that a browser won't dislpay a non-styled html if we place its css before it?
