Multiple accordion on a page
There are a couple of inconsistencies which you could tidy up. You're toggling classes to show/hide the div but using show/hide directly on the triggers. You're using chaining in one onClick but not in the other. And you're using the class to reference the accordion contents in one case, but the element name in the other.

$('.more').hide();

var learnMore = $('.learn-more'),
    close = $('.close');

learnMore.click(function() {
   $(this).hide().next('.more').show();
});

close.click(function() {
    $(this).parent().hide().prev('.learn-more').show();
});

is one possible way of making everything consistent, although you may prefer to always toggle classes instead (or to add animations).
