css - How can I reverse the order of columns in Bootstrap 4?

Question

I have this simple scenario:

<div class="row">
    <div class="col-md-12 col-lg-6 col-xl-7">A</div>
    <div class="col-md-12 col-lg-6 col-xl-5">B</div>
</div>

basically if md

A
B

I would like it, if md

B
A

I have tried many variants found on web, like flex-first and whatnot.. can't seem to get it to work

Any ideas?

If you want to change order on md and larger sizes you can use order-md-, this is provided by bootstrap. It looks like, if you want to change order only on md size you will have to define normal order on one larger size Fiddle

<div class="row">
  <div class="col-md-12 order-md-2">A</div>
  <div class="col-md-12 order-md-1">B</div>
</div>
