.col((@index + 1), ~"@{list}, @{item}");
}
.col(@index, @list) when (@index > @grid-columns) { // terminal
@{list} {
position: relative;
// Prevent columns from collapsing when empty
min-height: 1px;
// Inner gutter via padding
padding-left: ceil((@grid-gutter-width / 2));
padding-right: floor((@grid-gutter-width / 2));
}
}
.col(1); // kickstart it
}
难点1：
时候我们需要输出一些不正确的CSS语法或者使用一些 LESS不认识的专有语法.
要输出这样的值我们可以在字符串前加上一个 ~, 例如:
.class {
filter: ~"ms:alwaysHasItsOwnSyntax.For.Stuff()";
}
编译后：
.class { filter: ms:alwaysHasItsOwnSyntax.For.Stuff(); }
看下面领悟
.make-grid-columns() { // Common styles for all sizes of grid columns, widths 1-12 .col(@index) { // initial @item: ~".col-xs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}"; .col2((@index + 1), @item); } .col2(@index, @list) when (@index =< @grid-columns) { // general; "=<" isn‘t a typo @item: ~".col-xs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}"; .col2((@index + 1), ~"@{list}, @{item}"); } .col2(@index, @list) when (@index > @grid-columns) { // terminal @{list} { position: relative; // Prevent columns from collapsing when empty min-height: 1px; // Inner gutter via padding padding-left: ceil((@grid-gutter-width / 2)); padding-right: floor((@grid-gutter-width / 2)); item:~"@{item}"; list:~"@{list}" } } .col(1); // kickstart it }
