Bootstrap col align right

I'm trying to create a row with 2 cols. One col on the left with its contents aligned left, and the second col with its contents aligned right (old pull-right).

How to do I go about this in alpha-6?

I've tried a few things, but this is what I have so far. What am I missing?

<div class="row">
    <div class="col">left</div>
    <div class="col ml-auto">content needs to be right aligned</div>
</div>

Bootstrap 5 (update 2021)

To right align elements in Bootstrap 5...

float-right is now float-end
text-right is now text-end
ml-auto is now ms-auto

Bootstrap 4 (original answer)

Use float-right for block elements, or text-right for inline elements:

<div class="row">
     <div class="col">left</div>
     <div class="col text-right">inline content needs to be right aligned</div>
</div>
<div class="row">
      <div class="col">left</div>
      <div class="col">
          <div class="float-right">element needs to be right aligned</div>
      </div>
</div>

If float-right is not working, remember that Bootstrap 4 is now flexbox, and many elements are display:flex which can prevent float-right from working.

In some cases, the utility classes like align-self-end or ml-auto work to right align elements that are inside a flexbox container like the Bootstrap 4 .row, Card or Nav. The ml-auto (margin-left:auto) is used in a flexbox element to push elements to the right.

How about this? Bootstrap 4

<div class="row justify-content-end">
    <div class="col-3">
        The content is positioned as if there was
        "col-9" classed div appending this one.
    </div>
</div>
