Move single element to the end of a flex container

Question

I thought that I'd be able to shift this single button to the end of a flex-box.

I have set the parent to be a display: flex; and then I thought that I'd be able to target one element and pin it to the bottom of the container with align-self: flex-end;

It doesn't work. Here is my pen: My Codepen illustrating the issue

 <div class="row services">
  <div class="small-3 panel columns service">
    <i class="fa fa-thumbs-o-up"></i>
    <h3>SUSPENDISSE</h3><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. A, ad?</p>
    <div class="button">Read More</div>
  </div>
  <div class="small-3 panel columns service">
    <i class="fa fa-key"></i>
    <h3>MAECENAS</h3><p>Porro quibusdam nostrum eaque, quasi laudantium delectus quaerat cumque, quos.</p>
    <div class="button">Read More</div>
  </div>
  <div class="small-3 panel columns service">
    <i class="fa fa-flag"></i>
    <h3>ALIQUAM</h3><p>Iste architecto omnis, esse facere quod ratione, officia veritatis fugit.</p>
    <div class="button">Read More</div>
  </div>
  <div class="small-3 panel columns service">
    <i class="fa fa-flask"></i>
    <h3>HABITASSE</h3><p>Ducimus voluptates assumenda, illum adipisci sed quaerat est ipsum nisi.</p>
    <div class="button">Read More</div>
  </div>
</div>

.services {
  display: flex;

}
.service {
  flex-direction: column;
}
.button {
  align-self: flex-end;
}

Solution

align-self will only work with direct child elements of a flex parent, so:

• Make .service a flex parent with display: flex and set flex-wrap: wrap

• Center the button with margin: 0 auto

Working Example

Also available as a Codepen.

.services {
  display: flex;
}
.service {
  display: flex;
  flex-wrap: wrap;
}
.button {
  align-self: flex-end;
  margin: 0 auto !important; 
  /* !important used for this example only to override foundation.css*/
}
