I'm learning to use jquery, but am having difficulty in some fields.

I have a form where the input text has an image as background

<label>Label</label>

   <span class="Border-Left"></span>

      <span class="Background">

         <input type="Text" name="Name"/>

      </span>

   <span class="Border-Right"></span>

I wish that when the error appear, were added to the class "Error" in <span> (Border-Left, Background, Border-Right)

Excuse the bad English

Thanks.
