Reordering divs responsively with Twitter Bootstrap?

Question

I am working with Twitter Bootstrap v3 and want to reorder elements responsively, using column ordering and offsetting.

This is how I would like to use my elements.

Answer 1

I tried the push/pull as shown in the answer by Skelly but C ends up in a new row once heights are applied: http://www.bootply.com/Q3djHYawgb#

If B can be shown first when shown in small size, then I think it makes more sense to create a row inside the right hand side column to contain A and C:

<div class="containing row">
    <div class="b col-xs-12 col-md-6">Content of B</div>
    <div class="ac col-xs-12 col-md-6">
        <div class="row">
            <div class="a col-xs-12">Content of A</div>
        </div>
        <div class="row">
            <div class="c col-xs-12">Content of C</div>
        </div>
    </div>
</div>

Answer 2

The answer provided by @skelly is great starting point, but does cause some vertical alignment issues. Imagine A is a tall div, then C is vertically aligned below A.:

[A] [B]
[ ]
    [C]

Also, If you want to take this a step further you may also need to consider using clearfix blocks. For example;

<!-- Add clearfix for only the required viewport(s) -->
<div class="clearfix visible-md-block visible-lg-block"></div>

Without clearfix md or lg might end up as:

[A] [B]
    [C] [D]

This is particularly important if you want more than 2 elements in the final "column", or the heights of the elements start throwing other elements out of alignment.

With the clearfix md or lg would be:

[A] [B]
    [C]
    [D]

Answer 3

I think you want to look at the push and pull classes...

<div class="row">
   <div class="a col-xs-12 col-sm-12 col-md-6 col-lg-6 col-lg-push-6 col-md-push-6">Content of A</div>
   <div class="b col-xs-12 col-sm-12 col-md-6 col-lg-6 col-lg-pull-6 col-md-pull-6">Content of B</div>
   <div class="c col-xs-12 col-sm-12 col-md-6 col-lg-6 col-lg-push-6 col-md-push-6">Content of C</div>
</div>

Answer 4

Any reason to not use more traditional methods on this, ie. floating B left and the other elements to the right?

Like if you added this to current CSS in your jsfiddle:

.b {
    float: left;
    width: 50%;
    height: 100px;
}
.a, .c {
    float: right;
    width: 50%;   
    height: 50px;
}

I'm not sure that Bootstrap's column ordering could accomplish the stacking effect, perhaps only the re-ordering... Though the documentation is pretty slim on that feature.
