Introduction
The concept of templating is not new to web development. In fact, server-side templating languages/engines like Django (Python), ERB/Haml (Ruby), and Smarty (PHP) have been around for a long time. In the last couple of years however, we've seen an explosion of MVC frameworks spring up. All of them are slightly different, yet most share a common mechanic for rendering their presentational layer (aka da view): templates.
Let's face it. Templates are fantastic. Go ahead, ask around. Even its definition makes you feel warm and cozy:
template (n) - A document or file having a preset format, used as a starting point for a particular application so that the format does not have to be recreated each time it is used.
"...does not have to be recreated each time...." Don't know about you, but I love avoiding extra work. Why then does the web platform lack native support for something developers clearly care about?

It defines a new element which describes a standard DOM-based approach for client-side templating. Templates allow you to declare fragments of markup which are parsed as HTML, go unused at page load, but can be instantiated later on at runtime. To quote Rafael Weinstein:
They're a place to put a big wad of HTML that you don't want the browser to mess with at all...for any reason. Rafael Weinstein (spec author)
Feature Detection
To feature detect , create the DOM element and check that the .content property exists:
function supportsTemplate() { return 'content' in document.createElement('template'); } if (supportsTemplate()) { // Good to go! } else { // Use old templating techniques or libraries. }Declaring template content
The HTML element represents a template in your markup. It contains "template contents"; essentially inert chunks of cloneable DOM. Think of templates as pieces of scaffolding that you can use (and reuse) throughout the lifetime of your app.
To create a templated content, declare some markup and wrap it in the element:
