jquery - Changing CSS when changing select -

-

this working. i'm wondering why isn't affecting css of every .container within .filteritem. it's finding first 1 on page whereas want to change .container within .filteritem.

$(document).ready(function () {     $('#select').on('change', function () {         if (this.value == 'alltopics') {             $('.filteritem').fadein(500);         } else {             var elems = $('.filteritem[data-aa_eventtopic="' + this.value + '"]');             $('.filteritem').not(elems).closest('.filteritem').fadeout(500);             elems.closest('.filteritem').fadein(500);              //here             $('.filteritem').each(function () {                 settimeout(function () {                     $('.container').filter(':visible').first().css({                         bordertop: 'none',                         paddingtop: '0px'});                 }, 501);             });         }     }); });

i guess have rid of .first() call
