// Bootstrap Mid-Small - col-ms-* - the missing grid set for Bootstrap3.
//
// This is a hack to fill the gap between 480 and 760 pixels - a missing range
// in the bootstrap responsive grid structure. Use these classes to style pages
// on cellphones when they transition from portrait to landscape.
//
// NOTE: Here I use SASS instead of LESS for styling. To convert to LESS
// replace '$screen' with '@screen' and '$grid' with '@grid'.
//
// See https://github.com/twbs/bootstrap/issues/10203 for more info.

// Columns, offsets, pushes, and pulls for the ms device range, from phones

Hi, i´m new in bootstrap 3, think it´s amazing but i need to implement your hack since i have to creat a breakpoint in 480. Can you explain how to implement this hack? i´ve css/ js/ folders only, where and how i have to put this code?
Thanks!!

works great!

sujin2f commented Jan 23, 2014

Oh! Thank you :)

I'm using the SCSS version of bootstrap. I don't seem to be able to @import this after the bootstrap.scss @import as while the ms styles work, the md and lg styles then don't (as the ms are being defined afterwards). Is there a better way of using this without messing with the bootstrap core files?

AWESOME!!

Jakobud commented Apr 7, 2014

This appears to break the small, medium and large layouts when I add it. I removed the @import "bootstrap"; from the code, and then added the following at the bottom of bootstrap.scss:

@import "bootstrap/grid-ms";

Then I tried the following code:

<div class='container'>
    <div class='row'>
        <div class='col-xs-2 col-ms-4 col-sm-6 col-md-8 col-lg-10' style='background: red'>
            test
        </div>
        <div class='col-xs-10 col-ms-8 col-sm-6 col-md-4 col-lg-2' style='background: blue'>
            test
        </div>
    </div>
</div>

I see the xsmall and midsmall breakpoints work, but small, medium, and large don't work anymore. What did I do wrong here?

Can you PLEASE add visibility helper classes to this?

Great solution, to support visibility helper classes, you can add this at the top (providing you include bootstrap.less).
Note this is done in less.

@screen-xs-max: 480px; //overrides responsive-utilities
@screen-ms-max: 768px;

.visible-ms {
  @media (max-width: @screen-ms-max) {
    .responsive-visibility();
  }
}

.hidden-ms {
  @media (max-width: @screen-ms-max) {
    .responsive-invisibility();
  }
}

This is a hack for now because it's not supported in the main library.

Solution to Jakobud

replace

@media (min-width: $screen-xs) {
 .container { 
  @media (max-width: $screen-sm ) {
     max-width: $screen-sm - 20px;
   }
 }

to

@media (min-width: $screen-xs) and (max-width: $screen-xs-max) {
 .container { 
  @media (max-width: $screen-sm ) {
     max-width: $screen-sm - 20px;
   }
 }

Is this hack still working on Boostrap 3.2.0 ?

I think at line 18 the code should be :

@media (min-width: 480px) and (max-width: 768px) {

I'm working with BS 3.2.0 No issue yet after making this change.

Thank you for this hack.
It's also quite easy to implement this mixin version for us semantics nerds (in LESS):

@screen-ms-min: 480px;

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

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

Really very helpful, thanks a ton!!

This seems pretty useful but it doesn't include any licencing information. How do I know if I can use it?

I've forked this gist and changed the following:

  • added $screen-ms variables (min = 640, max = $screen-sm - 1)
  • added $container-ms variable
  • globally changed the $screen-xs-max to equal $screen-ms-min - 1 (so col-xs covers 480 to 639 as far as helpers are concerned)
  • added .visible-ms-* helpers
  • added .hidden-ms helper
  • container size reads from $container-ms

I am facing the same need for this breakpoint. The xs range is too wide up to 768px, remember that some desktops until few years were 640px. the range 480px to 768px is a good viewport for many uses not as a phone stacked range < 480px.

Noctim commented Feb 18, 2015

I'm facing the same problem as Jakobud!

the "col-ms-x" rule seems to overwrite everything "above" it. It's impossible to combine it with "col-sm-x" or "col-md-x", because they're getting completely ignored. Smaller sizes like "col-xs-x" seem to work.

Any workaround / fix so far?

Thanks for the gist and inspiration. I changed the naming to sx since for me ms always felt larger than sm. Here's my scss mixin https://gist.github.com/mediastuttgart/caa6e410c5aed8eebd92.

Great!! Thanks.

You can also add visibility adding this

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

Thanks a lot!

@Noctim: try hballesteros fix - it works for me.

Thanks! I'm using them in my current project.

I had the same issues as Jakobud. What i did was dumping the whole code into a .scss file, deleting the @import 'bootstrap' thing and replacing this

@media (min-width: $screen-xs) {
  .container {
    @media (max-width: $screen-sm ) {
      max-width: $screen-sm - 20px;
    }
  }

with this

@media (max-width: $screen-xs) {
  .container {
    @media (max-width: $screen-sm ) {
      max-width: $screen-sm - 20px;
    }
  }

Cheers mate. Thanks for the code.
