Which elements will load first in an html page?

Question

I want to know which elements (html tags, scripts, styles, images) will load first when opening a web page?

Can anybody help me? Thanks in advance.

There is no standard way; browsers are free to implement this in any way they like.

If you want to know how your browser does it, use a tool like Firebug, Chrome's Developer Tools or Safari Inspector. They can show the network traffic and in which order elements are downloaded.

Usually, the download order is the same as in the HTML document but browsers can open more than a single connection to a server. In that case, it might send 2 or 5 requests in document order but the server can respond in arbitrary order. Also some parts might be loaded from cache.
