How Can I Dynamically Generate Comma-Separated Class Lists in SCSS for Grid Systems?

Dynamically Generating Comma-Separated Class Lists in SCSS

In SCSS, constructing a grid system dynamically can prove challenging, particularly when seeking to generate a comma-separated list of column classes. To overcome this obstacle, the concept of @extend holds the key.

To initiate, define a mixin named col-x-list and utilize a @for loop to iterate through the desired number of columns. Within this loop, create class rules for each column, utilizing mixins like %float-styles to control styling. Employ @extend to inherit the %float-styles mixin, enabling the classes to share its properties.

For instance, consider the following code:

$columns: 12;

%float-styles {
  float: left;
}

@mixin col-x-list {
  @for $i from 1 through $columns {
      .col-#{$i}-m { @extend %float-styles; }
  }
}

@include col-x-list;

This code will generate the following CSS:

.col-1-m, .col-2-m, .col-3-m, .col-4-m, .col-5-m, .col-6-m, .col-7-m, .col-8-m, .col-9-m, .col-10-m, .col-11-m, .col-12-m {
  float: left;
}

By utilizing @extend, you can dynamically generate comma-separated class lists, allowing for greater flexibility and efficiency when creating dynamic grid systems in SCSS.
