<p>If a string is passed as the parameter to <code>$()</code>, jQuery examines the string to see if it looks like HTML (i.e., it has <code><tag ... ></code> somewhere within the string). If not, the string is interpreted as a selector expression, as explained above. But if the string appears to be an HTML snippet, jQuery attempts to create new DOM elements as described by the HTML. Then a jQuery object is created and returned that refers to these elements. You can perform any of the usual jQuery methods on this object:</p>

<p>If the HTML is more complex than a single tag without attributes, as it is in the above example, the actual creation of the elements is handled by the browser"s <code>innerHTML</code> mechanism. In most cases, jQuery creates a new <div> element and sets the innerHTML property of the element to the HTML snippet that was passed in. When the parameter has a single tag (with optional closing tag or quick-closing) — <code>$( "<img />" )</code> or <code>$( "<img>" )</code>, <code>$( "<a></a>" )</code> or <code>$( "<a>" )</code> — jQuery creates the element using the native JavaScript <code>createElement()</code> function.</p>

<p>For explicit parsing of a string to HTML, use the <ahref="/jQuery.parseHTML/">$.parseHTML()</a> method.</p>

<p>When passing in complex HTML, some browsers may not generate a DOM that exactly replicates the HTML source provided. As mentioned, jQuery uses the browser"s <code>.innerHTML</code> property to parse the passed HTML and insert it into the current document. During this process, some browsers filter out certain elements such as <code><html></code>, <code><title></code>, or <code><head></code> elements. As a result, the elements inserted may not be representative of the original string passed.</p>

<p>Filtering isn't, however, limited to these tags. For example, Internet Explorer prior to version 8 will also convert all <code>href</code> properties on links to absolute URLs, and Internet Explorer prior to version 9 will not correctly handle HTML5 elements without the addition of a separate <ahref="http://code.google.com/p/html5shiv/">compatibility layer</a>.</p>

<p>To ensure cross-platform compatibility, the snippet must be well-formed. Tags that can contain other elements should be paired with a closing tag:</p>
