Google Closure - positions sections horizontally with position:absolute

gistfile1.js

app.plateSections = function() {

	var plateWidth = 0;
	// Add the first section's width.
	goog.style.getSize( goog.dom.getFirstElementChild( goog.dom.getElement('plate') ) ).width ;
	// Position each of the sections horizontally one after another starting from the first child of plate.
	goog.array.forEach( goog.dom.getChildren( goog.dom.getElement('plate') ), function(section) {
		goog.style.setPosition( goog.dom.getNextElementSibling(section), goog.style.getPosition(section).x + goog.style.getSize(section).width );
		// Accumulate the width of each section after the first section.
		plateWidth += goog.style.getSize(section).width;
	});
	// Get the should-be width of the plate element.
	goog.style.setSize(goog.dom.getElement('plate'), plateWidth);
};
