Sure, if you mean the same two CSS classes that are applied to the header, but to the content DIVs as well. Inside ddaccordion.js, find and add to the two functions expandit() and collapseit() with the lines in red:
Code:
expandit:function($targetHeader, $targetContent, config, isclicked){
$targetContent.slideDown(config.animatespeed, function(){config.onopenclose($targetHeader.get(0), parseInt($targetHeader.attr('headerindex')), $targetContent.css('display'), isclicked)})
this.transformHeader($targetHeader, config, "expand")
$targetContent.addClass(config.cssclass.expand).removeClass(config.cssclass.collapse)
},
collapseit:function($targetHeader, $targetContent, config, isclicked){
$targetContent.slideUp(config.animatespeed, function(){config.onopenclose($targetHeader.get(0), parseInt($targetHeader.attr('headerindex')), $targetContent.css('display'), isclicked)})
this.transformHeader($targetHeader, config, "collapse")
$targetContent.addClass(config.cssclass.collapse).removeClass(config.cssclass.expand)
},
