CSS: How to remove pseudo elements (after, before,...)?
p:after { content: none;}none is the official value to set the content, if specified, to nothing.
You need to add a css rule that removes the after content (through a class)..
An update due to some valid comments.
The more correct way to completely remove/disable the :after rule is to use
p.no-after:after{content:none;}Original answer
You need to add a css rule that removes the after content (through a class)..
p.no-after:after{content:"";}and add that class to your p when you want to with this line
$('p').addClass('no-after'); // replace the p selector with what you need...a working example at : http://www.jsfiddle.net/G2czw/
