Question

I have the following class:

#categories_btn:after {
    content: "+";   
}

I am trying to use jquery to toggle this class to show either + or -. What is the best way to do this?

   $('#categories_btn a').click(function(){
     $('aside#left_col #categories').toggle();
   });

Answer 1

Add a class that has different :after content:

#categories_btn.alt:after {
    content: "-";   
}

Then toggle this class on the desired element using toggleClass('alt').
