Hi,

for anyone trying to restore the old look here is my attempt:

table.dataTable thead > tr > th.sorting:before, table.dataTable thead > tr > th.sorting:after, table.dataTable thead > tr > th.sorting_asc:before, table.dataTable thead > tr > th.sorting_asc:after, table.dataTable thead > tr > th.sorting_desc:before, table.dataTable thead > tr > th.sorting_desc:after, table.dataTable thead > tr > th.sorting_asc_disabled:before, table.dataTable thead > tr > th.sorting_asc_disabled:after, table.dataTable thead > tr > th.sorting_desc_disabled:before, table.dataTable thead > tr > th.sorting_desc_disabled:after,
table.dataTable thead > tr > td.sorting:before,
table.dataTable thead > tr > td.sorting:after,
table.dataTable thead > tr > td.sorting_asc:before,
table.dataTable thead > tr > td.sorting_asc:after,

table.dataTable thead > tr > td.sorting_desc:after,
table.dataTable thead > tr > td.sorting_asc_disabled:before,
table.dataTable thead > tr > td.sorting_asc_disabled:after,
table.dataTable thead > tr > td.sorting_desc_disabled:before,
table.dataTable thead > tr > td.sorting_desc_disabled:after {
  top: 0.5em;
  bottom: 0.5em;
  opacity: 0.3;
  line-height: 1.5em;
  font-size: 1em;
}

table.dataTable thead > tr > th.sorting:before, table.dataTable thead > tr > th.sorting_asc:before, table.dataTable thead > tr > th.sorting_desc:before, table.dataTable thead > tr > th.sorting_asc_disabled:before, table.dataTable thead > tr > th.sorting_desc_disabled:before,

    right: 1em;
    content: "\2191";
}

table.dataTable thead > tr > td.sorting_asc:before,
table.dataTable thead > tr > td.sorting_desc:after {
  opacity: 1;
