Display border under info row

Hi there – trying hard to format the listing as I’d like and trying to place a border under the info row. I have managed to delete the border under the active row by using a 0px size for the border but I cannot find a way to add the alternate border. I have tried:

.gigpress-info.active gigpress-alt {
border-bottom: 1px;
border-bottom-color: #fff;
border-bottom-style: dashed; }

This didn’t work for me.

I’ve used the same border CSS styles under:

.entry table tr:nth-child(even) {
border-bottom: 1px;
border-bottom-color: #fff;
border-bottom-style: dashed; }

Now in danger of pulling all my remaining hair out so thought I’d drop in this request.

All the best
Chris
