[Resolved] Add / between languages

Problem:
The client wants to format the language switcher in their website header to display languages with a '/' between them, specifically as 'EN/GR'.
Solution:
If you're experiencing this, we recommend you follow these steps:
1. Enable the language switcher.
2. Configure it to show only language codes by following the instructions here: https://wpml.org/forums/topic/use-language-abbreviations-in-menu-language-switcher/
3. Use custom CSS to add '/' between the languages. Here is an example of how you can do it:

.wpml-ls li.wpml-ls-item a:after {
   content: "/";
    margin-left: 13px;
}
.wpml-ls li:last-child.wpml-ls-item a:after {    
content: "";
}
