<p><em>Inherits methods from its parent, {{domxref("HTMLElement")}}, </em><em>and implements those from {{domxref("URLUtils")}}</em><em>.</em></p>

<dl>
 <dt>{{domxref("HTMLElement.blur()")}}</dt>
 <dd>Removes the  keyboard focus from the current element.</dd>
 <dt>{{domxref("HTMLElement.focus()")}}</dt>
