почему невозможно поменять свойства css
Почему не меняются свойства css в данном случае?
var width_= $('li.active').width()
$('li.active:after').css('border-right-width', width_/2+'px')
$('li.active:after').css('border-left-width',width_/2+'px')
ширину списка определяет |
У псевдо-элемента хочешь поменять?
