Consider the following HTML:

Html:

<h2>Greetings</h2>
<div class="container">
  <div class="inner">Hello</div>
  <div class="inner">Goodbye</div>
</div>

You can create content and insert it into several elements at once:

jquery:

$( ".inner" ).prepend( "<p>Test</p>" );

Each <div class="inner"> element gets this new content:

Html Result:
<h2>Greetings</h2>
<div class="container">
  <div class="inner">

    Hello
  </div>
  <div class="inner">
    <p>Test</p>
    Goodbye
  </div>
</div>
