<p><a href="#" title="That's what this widget is">Tooltips</a> can be attached to any element. When you hover
the element with your mouse, the title attribute is displayed in a little box next to the element, just like a native tooltip.</p>
<p>But as it's not a native tooltip, it can be styled. Any themes built with
<a href="http://jqueryui.com/themeroller/" title="ThemeRoller: jQuery UI's theme builder application">ThemeRoller</a>
will also style tooltips accordingly.</p>
<p>Tooltips are also useful for form elements, to show some additional information in the context of each field.</p>
<p><label for="age">Your age:</label><input id="age" title="0.25 = 15 mins <br>0.50 = 30 mins<br>0.75 = 45 mins<br>1.00 = 1 hour"></p>
<p>Hover the field to see the tooltip.</p>
