Bootstrap 3: adding a new set of columns

问题

I've been using Bootstrap 3 for a while and now I need to make a new set of extra small columns for horizontal mobiles (e.g. 384px screen width) and after this use it as follows:

col-xxs-1, col-xxs-2, col-xxs-offset-5, hidden-xxs, etc.

Are there some Bootstrap Less mixins for this purpose? I'm not sure how to use them

edit:

There is a Bootstrap mixin called .make-grid(), but I can't make it work.

Code for col-xxs-x,col-xxs-offset,col-xxs-push,col-xxs-pull:

Add this code:

.col-xxs-1, .col-xxs-2, .col-xxs-3, .col-xxs-4,
.col-xxs-5, .col-xxs-6, .col-xxs-7, .col-xxs-8,
.col-xxs-9, .col-xxs-10, .col-xxs-11, .col-xxs-12 {
    min-height: 1px;
    padding-left: 15px;
    padding-right: 15px;
    position: relative;
}

@media (max-width: 384px) {
    .col-xxs-1,
    .col-xxs-2,

    .col-xxs-5,
    .col-xxs-6,
    .col-xxs-7,
    .col-xxs-8,
    .col-xxs-9,
    .col-xxs-10,

Code for hidden-xxs:

Add this code:

Notice that Bootstrap's CSS uses a mobile first strategy, so it is important to define your xxs-grid (i should choose an other name) after the xs-grid but before the sm-grid. See also: Bootstrap 3 mixin multiple make-*-column.

For that reason you can not use the Less code from this question Bootstrap 3 extra large (xl) columns

Download the Bootstrap source code at: http://getbootstrap.com/getting-started/
in less/variables.less add:

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

Open less/grid.less change the .container class as follows:

.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;
  }

and between the Extra small grid and Small grid code add:

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

In the 'less/mixins/grid-framework.less' file replace twice @item: ~".col-xs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}"; with @item: ~".col-xs-@{index}, .col-xxs-@{index}, .col-sm-@{index}, .col-md-@{index}, .col-lg-@{index}";
And finally run grunt dist
1. (optional) add the following code to the /less/mixins/grid.less file

// 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));
  }
}

回答3:

this full implementation (including pull-push-offset-visible-hidden) will be implemented in v4 as mentioned by @mdo

here https://github.com/twbs/bootstrap/issues/10203#issuecomment-23823054

and here https://github.com/twbs/bootstrap/pull/12893.

A posible alternative is posted here https://github.com/donquixote/bootstrap-compiled/tree/xs-AB-subdivision.

回答4:

Others have more complex solutions, but really there is an easier solution. Because this is the smallest break point, you can just add the class yourself with the !important flag so that it overrides the larger column sizes (like this). I use the name col-tn-12 because that is what this break point will be called when Bootstrap 4 is rolled out.

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

回答5:

using the code from the alternative github that @facundo posted, I switched the first line from a min-width of 480px to a min-width of 0 and a max-width of 480px and it seemed to work for what I needed without having to use any other coding or files:

   @media (min-width: 0px) and (max-width:480px){
  .col-xs-B-1, .col-xs-B-2, .col-xs-B-3, .col-xs-B-4, .col-xs-B-5, .col-xs-B-6, .col-xs-B-7, .col-xs-B-8, .col-xs-B-9, .col-xs-B-10, .col-xs-B-11, .col-xs-B-12 {
    float: left;
  }
  .col-xs-B-12 {
    width: 100%;
  }
  .col-xs-B-11 {
    width: 91.66666667%;
  }
  .col-xs-B-10 {
    width: 83.33333333%;
  }
  .col-xs-B-9 {
    width: 75%;
  }
  .col-xs-B-8 {
    width: 66.66666667%;
  }

Thanks paulalexandru for this excellent and very usefull solution. I recently need to use the reseting offset option (col-xxs-offset-0) on smallest screens, so I had to add those few lines for it works well :

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

I post it here, maybe it would be usefull for thoses who may encounter this need too.

You could just remove the media queries for the columns from the css. That would mantain the width precentage of the columns on any screen size.

回答8:

You can use the following to accomplish this. I personally link to the bootstrap CDN in my projects and keep a local version of bootstrap so I can tap into its mixins for my site specific styles which is where I would place the following...

SCSS

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

Less

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