page/events/event-extensions.md - too big a note

[nikie]

Not sure how to fix, so opening an issue.

Note "Note: jQuery event extensions are an advanced feature..." at the beginning of page
page/events/event-extensions.md is rendered with too big font due to this line of CSS
http://learn.jquery.com/jquery-wp-content/themes/jquery/css/base.css?v=1:

content blockquote p {

background-color: #F2F2F2;
color: #828282;
font: italic 23px/26px "Helvetica Neue",Helvetica,Arial,Geneva,sans-serif;
