Pushing and Pulling Columns - Bootstrap 4 -


this need:

desktop: b a

mobile: 

a b

here html:

<div class="row">      <div class="col-md-7 col-sm-7 push-md-5">             </div>      <div class="col-md-5 col-sm-5 pull-md-7">         b     </div>  </div>

it in correct order on mobile device not on desktop. have tried couple of guides , material without luck. in guides moving equal columns 4 or 6 it's bit confusing understand clearly.

here go solution https://jsfiddle.net/kzmz7qal/1/

.div1{     background: blue;    color: #fff;  }    .div2 {    background: red;    color: #fff;  }
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" rel="stylesheet"/>  <div class="container-fluid">      <div class="row">        <div class="col-md-7 col-sm-7 push-sm-5 div1">               </div>        <div class="col-md-5 col-sm-5 pull-sm-7 div2">          b      </div>      </div>    </div>

i guess looking for... changed pull & push small screen (sm) rather medium screen (md)

pull works on left value (col value specified)

push works right (col value specified)
