define empty string variable

[vol4ok]

I want to define a variable, which could be empty in some cases @prefix: ""; and to use it like this src: url("@{prefix}/path/to/something"); the problem is that it compiles into src: url("""/path/to/something");

How to define an empty string variable, that can be compiled in src: url("/path/to/something");

I have the same issue! Try to use @prefix: " ";

[joeldrapper]

@prefix: "";
header {
    background: url('@{prefix}logo.png');
}

Works great for me. If that doesn't work you could change it to this which sets it to be empty with javascript.

@prefix: ~'';

I use: @prefix: ;

and its empty :)
