My site's header highlighting code.

nav-highlight.js

// Ignore the preceding '/'.
page = [removed].pathname.slice(1);  	
// The landing page corresponds to the 'home' icon.
if (page === '') page = 'home';
// Test if the page is a nav link.
page = page.match(/home|about|projects|blog/);
 // Check the result of the regex.
if (page && page.length > 0) {
  // Style the corresponding nav link.
	$('#' + page[0]).children().addClass('current-page');
}
