<p class="desc"><strong>Description: </strong>Selects all elements of type submit.</p>
<div class="longdesc"><p>The <code>:submit</code> selector typically applies to button or input elements. Note that some browsers treat <code><button></code> element as <code>type="default"</code> implicitly while others (such as Internet Explorer) do not. </p></div>
<h3 id="notes-0">Additional Notes:</h3>
<div class="longdesc"><ul><li>Because <code>:submit</code> is a jQuery extension and not part of the CSS specification, queries using <code>:submit</code> cannot take advantage of the performance boost provided by the native DOM <code>querySelectorAll()</code> method. For better performance in modern browsers, use <code>[type="submit"]</code> instead.</li></ul></div>
