循环中的SASS CSS重复变量

Question

我正在编写一些SASS来输出网格的几个列/行组合。它在现代浏览器中运行良好，因为它们都知道如何使用CSS的repeat()函数。当然，我必须为IE11和Edge开发。。。

我有一个函数，它输出1-12列和1-24行之间的所有组合(是的，这是很多输出，但这是必要的(。

.grid-container {
width:calc(100% + 10px);
margin-left:-5px;
margin-top:-5px;
position:relative;
&.s {
@for $column from 1 through 12 {
@for $row from 1 through 24 {
&#{$column}x#{$row} {
.grid {
-ms-grid-columns: 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr;
-ms-grid-rows: 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr 12fr;
grid-template-columns: repeat($column, calc((100% / #{$column})));
grid-template-rows: repeat($row, calc((100% / #{$row})));
grid-column-gap: 0px;
grid-row-gap: 0px;
}
}
}
}
}
}

现在，我正试图弄清楚如何使-ms-grid-columns和-ms-grid rows动态。现在，它只是为12x12网格构建的，但我希望它们具有正确数量的fr单元，这取决于输出的网格大小。

我发现LESS有一个merge功能，可以完美工作，但我不知道SASS 中是什么

Answer 1

您可以简单地递归地将某些内容附加到变量：

@function columns($n) {
$thing: '';
@for $count from 1 through $n {
$thing: #{$thing} 1fr;
}
@return $thing;
}

Answer 2

您必须将row和column分开。此外，对于-ms前缀，您必须使用带有postpass的AutoPrefixer。在线演示检查Autoprefixer。

@for $col from 1 through 12{
.grid-col-#{$col}{
grid-template-columns: repeat($col, calc(100% / #{$col}));
}
}
@for $row from 1 through 24{
.grid-row-#{$row}{
grid-template-rows: repeat($row, calc(100% / #{$row}));
}
}

带有Autoprefixer 的CSS输出
