Bootstrap 3: 添加新的列集合

Question

Bootstrap 3: 添加新的列集合

我使用过一段时间的 Bootstrap 3，现在需要为移动设备的水平屏幕（如 384px 屏幕宽度）制作一组新的额外小的列，并在此之后按以下方式使用：

col-xxs-1, col-xxs-2, col-xxs-offset-5, hidden-xxs 等。

是否有一些适用于此目的的 Bootstrap Less 混合器？我不确定如何使用它们。

编辑:

有一个名为 .make-grid() 的 Bootstrap 混合器，但我无法使其工作。

使用SASS在Bootstrap 4.x中现在更加容易：https://dev59.com/Y5ffa4cB1Zd3GeqP8n1A#37543791 - Carol Skelly

注意，Bootstrap的CSS采用移动优先策略，因此在定义xs-grid之后但在sm-grid之前定义您的xxs-grid（我应该选择另一个名称）非常重要。参见：Bootstrap 3 mixin multiple make-*-column。

因此，您无法使用此问题中的Less代码：Bootstrap 3 extra large (xl) columns

从http://getbootstrap.com/getting-started/下载Bootstrap源代码。
在less/variables.less中添加：

-

// horizontal mobiles
@screen-xxs-min:             384px;
@container-xxs: (336px + @grid-gutter-width);

打开 less/grid.less 文件，将 .container 类修改为以下内容：

-

.container {
  .container-fixed();
  @media (min-width: @screen-xxs-min) {
    width: @container-xxs;
  }

  @media (min-width: @screen-sm-min) {
    width: @container-sm;
  }
  @media (min-width: @screen-md-min) {
    width: @container-md;
  }
  @media (min-width: @screen-lg-min) {
    width: @container-lg;
  }

在Extra small网格和Small网格的代码之间添加：

@media (min-width: @screen-xxs-min) {
  .make-grid(xxs);
}

在'less/mixins/grid-framework.less'文件中两次将@item: ~".col-xs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}";替换为@item: ~".col-xs-@{index}, .col-xxs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}";
最后运行grunt dist

(可选) 将以下代码添加到/less/mixins/grid.less文件中

// Generate the small columns
.make-xxs-column(@columns; @gutter: @grid-gutter-width) {
  position: relative;
  min-height: 1px;
  padding-left:  (@gutter / 2);
  padding-right: (@gutter / 2);

  @media (min-width: @screen-xxs-min) {
    float: left;
    width: percentage((@columns / @grid-columns));
  }
}
.make-xxs-column-offset(@columns) {
  @media (min-width: @screen-xxs-min) {
    margin-left: percentage((@columns / @grid-columns));
  }
}
.make-xxs-column-push(@columns) {
  @media (min-width: @screen-xxs-min) {
    left: percentage((@columns / @grid-columns));
  }
}
.make-xxs-column-pull(@columns) {
  @media (min-width: @screen-xxs-min) {
    right: percentage((@columns / @grid-columns));
  }
}

请您检查一下这个Gist https://gist.github.com/ctf0/3d9d35ffd681c924e940 并告诉我是否还需要其他内容？ - ctf0

我认为你应该将 @media @xxs { width: @container-xxs; } 替换为 @media @xs { width: @container-xxs; }。我也不确定为什么要使用 col-lg-0-5 等等，可能更好的方法是将 @grid-columns 设置为 24？ - Bass Jobsen

将列设置为24会产生相同的效果，但需要更多时间来计算确切的大小，例如“在24 3 = 1.5中，在12中”，然而这仍然是有价值的信息，我的主要问题是新的“xxs”是否可以像本机一样级联而不编写所有类？ @http://stackoverflow.com/questions/27750661/custom-classes-for-bootstrap?noredirect=1#comment43950529_27750661 - ctf0

将您的Gist中建议更改的媒体查询是否未能解决您的问题？能否详细说明您的问题？ - Bass Jobsen

很遗憾，它没有达到预期效果。我想要的是给一个div添加col-xs-3类，这样该div的大小将与您编写col-xs-3 col-sm-3 col-md-3 col-lg-3时相同。我希望使用我的新col-xxs类来实现相同的行为，明白我的意思吗？ - ctf0

谢谢。如果您能添加“hidden-xxs”和“visible-xxs”的说明，那就太好了。 - Jay Regal

这个完整的实现（包括pull-push-offset-visible-hidden）将在v4中实现，正如@mdo所提到的。

其他人可能有更复杂的解决方案，但实际上有一个更简单的解决方法。因为这是最小的断点，您可以使用!important标志自己添加类，以便覆盖较大的列大小（像这样）。我使用名称col-tn-12，因为这就是Bootstrap 4推出时这个断点的名称。

@media (max-width: 480px) {
    .col-tn-12 {
        width: 100% !important
    }
}

使用@facundo发布的备用github代码，我将第一行从最小宽度480px切换到最小宽度为0和最大宽度为480px，并且似乎可以满足我的需求，而无需使用任何其他编码或文件：

感谢paulalexandru提供这个优秀且非常有用的解决方案。最近我需要在最小的屏幕上使用重置偏移选项（col-xxs-offset-0），所以我不得不添加几行代码来使其正常工作：

@media (max-width: 480px) {
    .col-xxs-pull-0 {
        right: 0;
    }
    .col-xxs-push-0 {
        left: 0;
    }
    .col-xxs-offset-0 {
        margin-left: 0;
    }
}

我在这里发布，也许对那些可能遇到这种需求的人有用。

您可以从CSS中删除列的媒体查询。这将在任何屏幕尺寸上保持列的宽度百分比。

- Roberto Contardo Wirth

我不想失去其他的设置（xs-sm-md-lg） - Facundo Colombier

你可以使用以下方法来完成这个任务。我个人在我的项目中链接到Bootstrap CDN，并保留本地版本的Bootstrap，这样我就可以利用它的mixin来获取我的网站特定的样式，这也是我会放置以下内容的地方...。

SCSS

@media (max-width: $screen-xs-min) {
  @include make-grid(xxs);
}

少

@media (max-width: @screen-xs-min) {
  .make-grid(xxs);
}

- Adam Youngers

这是Sass（SCSS）代码。您不需要为新网格创建.container类或列类。 - Bass Jobsen

th.hidden-xxs,

        display: none !important;
    }

    tr.hidden-xxs.hidden-xs {
        display: none !important;
    }

    th.hidden-xxs.hidden-xs,
    td.hidden-xxs.hidden-xs {
        display: none !important;

}

@media (min-width: 768px) and (max-width: 991px) {

    .hidden-xxs.hidden-sm {
        display: none !important;
    }

    tr.hidden-xxs.hidden-sm {
        display: none !important;
    }

    th.hidden-xxs.hidden-sm,
    td.hidden-xxs.hidden-sm {
        display: none !important;
    }

}

@media (min-width: 992px) and (max-width: 1199px) {

    .hidden-xxs.hidden-md {
        display: none !important;
    }

    tr.hidden-xxs.hidden-md {
        display: none !important;
    }

    th.hidden-xxs.hidden-md,
    td.hidden-xxs.hidden-md {
        display: none !important;
    }

}

@media (min-width: 1200px) {

    .hidden-xxs.hidden-lg {
        display: none !important;
    }

    tr.hidden-xxs.hidden-lg {
        display: none !important;
    }

    th.hidden-xxs.hidden-lg,
    td.hidden-xxs.hidden-lg {
        display: none !important;
    }

}

@media (max-width: 384px) {

    .hidden-xs.hidden-xxs {
        display: none !important;
    }

    tr.hidden-xs.hidden-xxs {
        display: none !important;
    }

    th.hidden-xs.hidden-xxs,
    td.hidden-xs.hidden-xxs {
        display: none !important;
    }

}

@media (max-width: 384px) {

    .hidden-sm.hidden-xxs {
        display: none !important;
    }

    tr.hidden-sm.hidden-xxs {
        display: none !important;
    }

    th.hidden-sm.hidden-xxs,
    td.hidden-sm.hidden-xxs {
        display: none !important;
    }

}

@media (max-width: 384px) {

    .hidden-md.hidden-xxs {
        display: none !important;
    }

    tr.hidden-md.hidden-xxs {
        display: none !important;
    }

    th.hidden-md.hidden-xxs,
    td.hidden-md.hidden-xxs {
        display: none !important;
    }

}

@media (max-width: 384px) {

    .hidden-lg.hidden-xxs {
        display: none !important;
    }

    tr.hidden-lg.hidden-xxs {
        display: none !important;
    }

    th.hidden-lg.hidden-xxs,
    td.hidden-lg.hidden-xxs {
        display: none !important;
    }
}

同时替换：

@media (max-width: 767px) {

使用:

@media (min-width: 385px) and (max-width: 767px) {

在bootstrap.css中的这4个块内：

visible-xxs的代码：

添加以下代码：

.visible-xxs {
    display: none !important;
}

tr.visible-xxs {
    display: none !important;
}

th.visible-xxs,
td.visible-xxs {
    display: none !important;
}

@media (max-width: 384px) {

    .visible-xxs {
        display: block !important;
    }

    tr.visible-xxs {
        display: table-row !important;
    }

    th.visible-xxs,
    td.visible-xxs {
        display: table-cell !important;
    }

}

@media (min-width: 385px) and (max-width: 767px) {

    .visible-xxs.visible-xs {
        display: block !important;
    }

    tr.visible-xxs.visible-xs {
        display: table-row !important;
    }

    th.visible-xxs.visible-xs,
    td.visible-xxs.visible-xs {
        display: table-cell !important;
    }

}

@media (min-width: 768px) and (max-width: 991px) {

    .visible-xxs.visible-sm {
        display: block !important;
    }

    tr.visible-xxs.visible-sm {
        display: table-row !important;
    }

    th.visible-xxs.visible-sm,
    td.visible-xxs.visible-sm {
        display: table-cell !important;
    }

}

@media (min-width: 992px) and (max-width: 1199px) {

    .visible-xxs.visible-md {
        display: block !important;
    }

    tr.visible-xxs.visible-md {
        display: table-row !important;
    }

    th.visible-xxs.visible-md,
    td.visible-xxs.visible-md {
        display: table-cell !important;
    }

}

@media (min-width: 1200px) {

    .visible-xxs.visible-lg {
        display: block !important;
    }

    tr.visible-xxs.visible-lg {
        display: table-row !important;
    }

    th.visible-xxs.visible-lg,
    td.visible-xxs.visible-lg {
        display: table-cell !important;
    }

}

@media (max-width: 384px) {

    .visible-xs.visible-xxs {
        display: block !important;
    }

    tr.visible-xs.visible-xxs {
        display: table-row !important;
    }

    th.visible-xs.visible-xxs,
    td.visible-xs.visible-xxs {
        display: table-cell !important;
    }

}

@media (max-width: 384px) {

    .visible-sm.visible-xxs {
        display: block !important;
    }

    tr.visible-sm.visible-xxs {
        display: table-row !important;
    }

    th.visible-sm.visible-xxs,
    td.visible-sm.visible-xxs {
        display: table-cell !important;
    }

}

@media (max-width: 384px) {

    .visible-md.visible-xxs {
        display: block !important;
    }

    tr.visible-md.visible-xxs {
        display: table-row !important;
    }

    th.visible-md.visible-xxs,
    td.visible-md.visible-xxs {
        display: table-cell !important;
    }

}

@media (max-width: 384px) {

    .visible-lg.visible-xxs {
        display: block !important;
    }

    tr.visible-lg.visible-xxs {
        display: table-row !important;
    }

    th.visible-lg.visible-xxs,
    td.visible-lg.visible-xxs {
        display: table-cell !important;
    }

}

并且替换：

@media (max-width: 767px) {

使用:

@media (min-width: 385px) and (max-width: 767px) {
