如何使用 SASS 为不同的网格列和断点自定义 Bootstrap 4？

Question

各位开发者，

我试图在大尺寸上获得 12 列和 24 个装订线尺寸，而在一个容器视图中中等和较低时获得 6 列和 18 个装订线，而另一个容器视图在大尺寸上将是 15 列和 12 个装订线在较低的视图上相应地调整大小？？

这是我可以在前者上实现的（12 col 24 gutters，6 columns 18 gutters）：

background-grid {

@include make-row();

@include make-col-ready;



@each $breakpoint in map-keys($grid-breakpoints) {

    @include media-breakpoint-up($breakpoint) {

        //@include make-col(map-get($dani-number-col, $breakpoint ));

        .row.no-gutters {

            margin-right: map-get($dani-row-no-gutters, $breakpoint );

            margin-left: map-get($dani-row-no-gutters, $breakpoint );

        }         

        .row > .col,

        .row > [class*="col-"] {

            margin-right: map-get($dani-gutters, $breakpoint );

            margin-left: map-get($dani-gutters , $breakpoint );

        }

    }

}

}

虽然我尝试创建另一个容器类来处理另一个视图（15 列，6 个排水沟），但我无法理解它。主要是因为我对 CSS 和 SASS 的理解可能比较稀疏，尝试了谷歌搜索，但似乎没有合适的教程？

.foreground-container {

width: 1428px;

@include make-foreground-container();



@each $breakpoint in map-keys($grid-breakpoints) {

    @include media-breakpoint-up($breakpoint) {

        //@include make-col(map-get($dani-number-col, $breakpoint ));

        // @include make-col(15);

        .foreground-row {

            margin-right: map-get($dani-row-no-gutters, $breakpoint );

            margin-left: map-get($dani-row-no-gutters, $breakpoint );

        }         

        .foreground-row > .foreground-col,

        .foreground-row > [class*="foreground-col"] {

            margin-right: map-get($dani-row-no-gutters, $breakpoint );

            margin-left: map-get($dani-row-no-gutters, $breakpoint );

        }

    }

}

}

.foreground-row {

    @include make-foreground-row();

    // @include make-col(12);

}



.foreground-col {

    @include make-col-ready();

    @include make-col(15);

}

HTML、CSS

<div class="background-container">
  <div class="container">
    <div class="row">
      <div class="col">col1</div>
      <div class="col">col2</div>
      <div class="col">col3</div>
    </div>
  </div>
</div>

<div class="foreground-container">
  <div class="container">
    <div class="row">
      <div class="col">col1</div>
      <div class="col">col2</div>
      <div class="col">col3</div>
    </div>
  </div>
</div>

这甚至可能吗？如果是这样，如何以及如果不是实现我想要实现的目标的好方法？

谢谢。

您可以制作自定义 mixin 以在自定义容器内重新生成适当的断点列...

@mixin make-grid-columns-custom($columns: $grid-columns, $gutter: $grid-gutter-width, $breakpoints: $grid-breakpoints) {

  @each $breakpoint in map-keys($breakpoints) {
    $infix: breakpoint-infix($breakpoint, $breakpoints);

    // only override lg and up
    @include media-breakpoint-up('lg', $breakpoints) {
      @for $i from 1 through $columns {
        .col#{$infix}-#{$i} {
          padding-right: ($gutter / 2);
          padding-left: ($gutter / 2);
          @include make-col($i, $columns);
        }
      }

    }
  }
}

@import "bootstrap";

$foreground-container-max-widths: (
  sm: 600px,
  md: 800px,
  lg: 1000px,
  xl: 1428px
);

/* make the container for the custom grid */
.foreground-container > .container {
    @include make-container();
    @include make-container-max-widths($foreground-container-max-widths, $grid-breakpoints);
}

.foreground-container {
    /*  custom col for all breakpoints */
    @include make-grid-columns(6, 3px, $grid-breakpoints);

    /* override lg and up using custom mixin */
    @include make-grid-columns-custom(15, 6px, $grid-breakpoints);
}
