How to position an element such that it neatly rests under a wrapped line

Question

Using CSS, I want to be able to make the buttons move up if there is empty space (due to text wrapping).

The picture below illustrates the problem. I want the top button to be displayed a few pixels higher, as there is no text directly above it.

Instead, it is aligned with the bottom of text-which-is-only-present-on-the-right.

Is there a way of achieving this with CSS (I can change the HTML)?

<div class="right">
  <button class="button-primary">Do that...</button>
</div>

CSS:

div.right {
  text-align: right;
}

Answer 1

div {
  display:inline-block;
  width:100%;
  border: 1px solid #000;  
}

p {
  display:inline;
}

.button-primary {   
  float:right;
}
