/-- 30px --//------ * -------/

Answer 1

<div style="left:0;width:30px;"></div>
<div style="left:30px;right:0;"></div>

You may need to make them absolute positioned and the parent relative.

Answer 2

Better not to use absolute position, since you may want to place it within other elements. That's what works for me:

<div>
  <div style="float: left; width: 30px">1</div>
  <div>2</div>
</div>
