I have the following bit of LESS code working
@iterations: 940;
@iterations: 940;
@col:2.0833333333333333333333333333333%;
This whole question was very helpful to me. I just wanted to post the solution to my problem as the way to do it has changed since LESS v 1.4
. LESS Changelog
Rather than using the ~
sign, you just write out the portion of the name that you want along with the normal @
and variable name with {}
surrounding it. So: #class@{variable}
.
For example, my solution using the same sort of loop became such:
/*Total number of passport inserts*/
@numInserts: 5;
/*Total width of the passport foldouts*/
@passportWidth: 300px;
/*Change in passport insert width per iteration*/
@passportWidthDiff: (@passportWidth / @numInserts);
/*"Array" of colors to select from to apply to the id*/
@passportColors:
blue orange green red yellow
purple white teal violet indigo;
/*The faux loop the doesn't end up in the final css
@index is the counter
@numInserts is the total number of loops*/
.loopingClass (@index) when (@index <= @numInserts){
/*This is the created ID with the index appended to it
You can also do this with classes such as if
we had had ".insert@{index}"*/
#insert@{index}{
/*Here are our properties that get adjusted with the index*/
width: (@passportWidth - (@passportWidthDiff * (@numInserts - @index)));
height: 50px;
background-color: extract(@passportColors, @index);
z-index: (@numInserts - @index);
}
/*Here we increment our loop*/
.loopingClass(@index + 1);
}
/*This calls the loop and starts it, I started from 1
since I didn't want to lead a className starting from 0,
But there is no real reason not to. Just remember to
Change your conditional from "<=" to "<"*/
.loopingClass(1);
And produces the following:
#insert1 {
width: 60px;
height: 50px;
background-color: #0000ff;
z-index: 4;
}
#insert2 {
width: 120px;
height: 50px;
background-color: #ffa500;
z-index: 3;
}
#insert3 {
width: 180px;
height: 50px;
background-color: #008000;
z-index: 2;
}
...
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.
