I'm using Crunch it to compile the bootstrap.less but throws a syntax
error in 'mixins.less' in 'the grid' section:
line 522:
(~".span@{index}") { .span(@index); }
and all the following lines matching the format
(~".offset@{index}") { .offset(@index); }
(~"input.span@{index}, textarea.span@{index}, .uneditable-
input.span@{index}") { .span(@index); }
When I use SimpLESS 1.3
it stops at line 27 in progress-bars.less and says it's a syntax error
@keyframes progress-bar-stripes {
