Align elements relative to each other

Question

Basically I'm wondering if you can position 2 elements relative to each other. I have a h1 and h2 inside a div, I want to align the h2 to the right side of the h1

html

<header>
  <div>
    <h1>Header with some text</h1>
    <h2>Other header</h2>
  </div>
  <div>
  </div>
  <div>
  </div>
</header>

css

header { 
  width: 960px;
}

div {
  width: 318px;
  float: left;
  border: 1px solid red;
  min-height: 200px;
}

h1, h2 {
  font-size: 16px;
}

Answer 1

The simplest solution is to wrap the headings in an extra inline-block div and the apply text-align:right.

.parent {
  width: 80%;
  border: 1px solid red;
}
.wrap {
  display: inline-block;
  text-align: right;
}

<div class="parent">
  <div class="wrap">
    <h1>
I'm a really long h1 tag
</h1>
    <h2>
 Short h2 tag
</h2>
  </div>
</div>
