		<p>jQuery UI is a curated set of user interface interactions, effects,

			If you're new to jQuery UI, you might want to check out our
			<a href="https://jqueryui.com/" title="jQuery UI">main site</a> for
			more information and full demos. If you're new to jQuery, you might
			also be interested in the <a href="https://learn.jquery.com/">jQuery
			Learning Center</a> tutorials.</p>

		<p>This site provides API documentation for jQuery UI <?php echo $thisVersion; ?>. If
			you're working with an older version, you can find the API documentation

			and enhancements. Check out the
