li:last-child

Hi,

I’m working with the enfold template for a restaurant. I’m using the catalog list to display the various menu

I’ve added the word “or” between the different terms of a same list thanks to
.av-catalogue-list li:after { content: "or";}
Dishe 1
or
Dishe 2

I’ve encounter a problem with the last-child term : whatever i’m doing…it’s always displayed

.av-catalogue-list li:after { content: "or"}
.av-catalogue-list li:last-child > after  {border-bottom: none;content: ""}

May I’ve your advice not to display this last child ?
Many Many thanks
