How do I escape a backslash in LESS?

Question

I'm having some issues escaping a backslash in LESS. Here's my code:

&.room {
    &:after {
        content:"\";
    }
}

Any help would be greatly appreciated, many thanks.

Answer 1

Just ran into this issue, Escaping quotes keeps the escape backslash in

content: ~"\"";

produces

content: \";

Can refer to the official repository of less. ISSUES

OR as @SLC mentioned, can use double backslash.

Answer 2

&.room {
    &:after {
        content:"\\";
    }
}
