Center multiple 's over image without extra s in CSS

Imagine you have the following construction:

   <div>
       <img ...>
       <h3> Some h3 text </h3>
       <h2> Some h2 text </h2>
   </div>

Is it possible to center <h3> and <h2> over <img> without creating a new <div>? (<h3> and <h2> should not overlap). So I need basically a pure CSS solution. Thank you in advance.
