Finding code in the admin - newsletter signup

[VisHorizons]

I'm trying to edit the layout of my newsletter/catalog boxes above the footer.

I'm having some trouble locating some code.

Here's a picture of my code. The left is the code on the site, the right is the code in Miva.

<div class="newsletter-catalog">
  <div id="newsletter-signup" class="readytheme-contentsection">
    <div class="row">

In the admin:
The first line ("newsletter-catalog") are in the Global Footer.

The third line ("row") is in Ready Theme>Content Sections>newsletter-signup

I can't find the second line ("newsletter-signup") in Miva admin.

That second line is output by Miva as a wrapper for the contents within the ReadyTheme Content section. The ID is based on the code of the section and the class is the type of ReadyTheme element. Both of these can be overridden by setting the ID or Class values in the ReadyTheme Content section.
