Dynamic class names in LESS

Question

I have the following bit of LESS code working

            @iterations: 940;
            @iterations: 940;
            @col:2.0833333333333333333333333333333%;
           


        

Answer 1

I don't think you're far off. What I've done is create a second variable inside the mixin, called @index2. All this does is find the '920px minus @index' value that you're looking for:

@index2 = (920-@index);

this is then appended to the class name:

(~".gs@{index}-@{index2}") {

This is the complete loop:

.loopingClass (@index) when (@index > 160) {
    @index2 = (920-@index);
    // create the actual css selector, example will result in
    // .myclass_30, .myclass_28, .... , .myclass_1
    (~".gs@{index}-@{index2}") {
    // your resulting css
        width: (@index/20+1)*@col;
    }
    // next iteration
    .loopingClass(@index - 60);
}
// "call" the loopingClass the first time with highest value
.loopingClass (@iterations);

In order to get just the set you are looking for (gs220-700 to gs700-220), just change @iterations to equal 700.

Worth noting that currently, this will create the classes in the reverse order of how you specified them in the question.
