alloy:headHead is a UIOutput that renders a
<head>element for webapps, but not for portlets. In the case of portlets, the presence of alloy:head informs the JSF portlet bridge that JSF resources with
target="head"should be included in the
<head>element rendered by the portal.
Since it extends HtmlHead, it supports all the features of h:head. However, the main benefit of using alloy:head instead of h:head is that all of the Liferay Faces Alloy resources (such as alloy.js) are automatically included in the
General UsageThe usage of alloy:head in webapps is the same as with portlets. However, the surrounding tag in a webapp is
<html>whereas the surrounding tag in a portlet is f:view.
