How to set the class of the root div in an Ember application?
<p>I have an <strong>Ember 2.3.0</strong> application. When the application is initialized, Ember creates a root <code>div</code> inside which, everything I create is inserted. This <code>div</code> looks like this:</p>

<pre><code>&lt;div id="ember351" class="ember-view"&gt;&lt;/div&gt;
</code></pre>

<p>This element is a <strong>first child</strong> of the <code>&lt;body&gt;</code> element. I need to be able to set the class of this <code>div</code>.</p>

<p>How do I do that?</p>
