How do you enclose unknown HTML in a div with plain Javascript?
<p>I have an HTML page that has varying types of content. I would like to make a javascript function that when run encloses anything inside the <code>&lt;body&gt;</code> tag with a <code>&lt;div id="content-container"&gt;</code>. Then I want to be able to add a <code>&lt;div id="verifying"&gt;&lt;/div&gt;</code> that new <code>&lt;div&gt;</code>. I think I know how to do this with jQuery, but I need to do it with plain Javascript. </p>

<p>Any idea as to how this would be done?</p>
