In essence, everything will move in a serial process and future processes will be "blocked" from occurring until after this takes place. This is also referred to as single threaded. More commonly as you may already be aware of, JavaScripts are called upon in the footer of the page, typically before the last body tag or by way of self-construction through use of an anonymous or immediate function, which only builds itself once the DOM is already parsed. [ 22 ] Chapter 2 The async attribute Even more recently, included page scripts can have the async attribute added to their tag elements, which will tell the browser to download other scripts in parallel.

The only thing is, we have a fixed element currently occupying some real estate at the top of the page, so we'll need to compensate for that. This is done by using jQuery to keep track of how high the navigation is and then subtracting that from the position the page would normally animate to. The very last part, which is returning false, is removing the default activity that the browser would normally do, which would have been to add the href attribute up into the top address bar, before jumping down to that section of the page, similar to the way the name attribute would work as an anchor in the page's content.

Jquery); [ 21 ] Installing Modernizr Blocking versus non blocking The reason we've put this library into the head of the HTML page and not the footer is because we actually want Modernizr to be a blocking script; this way it will test for, and if applicable create or shim, any elements before the DOM is rendered. We also want to be able to tell what features are available to us before the page is rendered. The script will load, Modernizr will test the availability of the new semantic elements, and if necessary, shim in the ones that fail the tests, and the rest of the page load will be on its merry way.
