jQuery Itself - what can it do?

Notice that it has counted the <li> items and added a note to the page indicating how many it found. This in itself is not very useful, but it shows you how jQuery works. What if you now wanted to turn those items red? Or only the ones that were PDFs?

Code on this page:

$('<br /><p class="commentary>Page contains ' + $('li').length + ' &lt;li&gt; elements!</p>')
.css("background-color", "#FF0")

.css("border", "3px solid red")
.appendTo('body');

return to first page
