[twitter-bootstrap] col align right

For Bootstrap 4 I find the following very handy because:

  • the column on the right takes exactly the space it needs and will pull right
  • while the left col always gets the maximum amount of space!.

It is the combination of col and col-auto which does the magic. So you don't have to define a col width (like col-2,...)

<div class="row">
    <div class="col">Left</div>
    <div class="col-auto">Right</div>
</div>

Ideal for aligning words, icons, buttons,... to the right.

An example to have this responsive on small devices:

<div class="row">
    <div class="col">Left</div>
    <div class="col-12 col-sm-auto">Right (Left on small)</div>
</div>
