How to order divs in bootstrap 4? [duplicate]

问题

I have to divs next to each other in a row div. On mobile, i want the right_side div(col-md-9) to be the first div.

I tryed ordering it with flex, but it messed up all my site.

<div class="row">
   <div class="col-md-3">Left side</div>
   <div class="col-md-9">Right side, but first on mobile or tablet</div>
   <div class="clearfix"></div>
</div>

If i am viewing the site on mobile or tablet, i want the col-md-9 div as first div.

回答1:

there is an option to reverse the row using class. here is the code please try it once.

<div class="row flex-row-reverse">
   <div class="col-md-9">Right side, but first on mobile or tablet</div>
   <div class="col-md-3">Left side</div>
   <div class="clearfix"></div>
</div>

@media screen and (max-width: 767px) {
  .col-md-3 {
    order: 2;
  }
  .col-md-9 {
    order: 1;
  }
}

Just use order property.

@media only screen and (max-width: 760px) {
  .col-md-3 {
 order:2;
  }
}

@media only screen and (max-width: 760px) {
  .col-md-3 {
 order:2;
  }
}

<div class="row">

</div>

Use Column Ordering to accomplish this.

col-md-push-6 will "push" the column to the right 6 and col-md-pull-6 will "pull" the column to the left on "md" or greater view-ports. On any smaller view-ports the columns will be in normal order again.

I think what throws people off, is that you have to put B above A in your HTML. There may be a different way to do this where A can go above B in the HTML, but I'm not sure how to do it...

See Code

<div class="row">
  <div class="col-md-6 col-md-push-6">B</div>
  <div class="col-md-6 col-md-pull-6">A</div>
</div>

view-port >= md

|A|B|

view-port < md

|B|
|A|

you can do with flex and order as below example.

If it is messing-up with all sites, then give your custom class and then give CSS.

@media screen and (max-width: 531px) {
    .row { display: flex; flex-direction: column; }
    .two { order: 1; }
    .one { order: 2 }
}

<div class="row">
   <div class="col-md-3 one">Left side</div>
   <div class="col-md-9 two">Right side, but first on mobile or tablet</div>
   <div class="clearfix"></div>
</div>
