Вопрос по – Динамические имена классов в LESS

10

У меня следующий бит LESS кода работает

            @iterations: 940;
            @iterations: 940;
            @col:2.0833333333333333333333333333333%;
            // helper class, will never show up in resulting css
            // will be called as long the index is above 0
            .loopingClass (@index) when (@index > -20) {
                // create the actual css selector, example will result in
                // .myclass_30, .myclass_28, .... , .myclass_1
                (~"[email protected]{index}") {
                    // your resulting css
                    width: (@index/20+1)*@col;
                }
                // next iteration
                .loopingClass(@index - 60);
            }
            // end the loop when index is 0
            .loopingClass (-20) {}
            // "call" the loopingClass the first time with highest value
            .loopingClass (@iterations);

Он выводит нашу сеточную систему так:

            .gs940 {
              width: 100%;
            }
            .gs880 {
              width: 93.75%;
            }
            .gs820 {
              width: 87.5%;
            }
            .gs760 {
              width: 81.25%;
            }
            .gs700 {
              width: 75%;
            }

и т. д. и т. д.

Теперь, что я хочу сделать, это немного математики для имен классов, чтобы произвести следующие классы

            .gs220-700
            .gs280-640
            .gs340-580
            .gs400-520
            .gs460-460
            .gs520-400
            .gs580-340
            .gs640-280
            .gs700-220

и т. д. и т. д.

в основном это будет                 . (@ index) - (920px минус @index)

Но я понятия не имею, возможно ли это.
