The HTML generated output just underneath the header is substantially different, up to the <article>, and after. I just included the part up to the article element.
2.6.3:
<div id="content" class="col-full">
<section id="main" class="col-left">
<article class="post-950 post type-post status-publish format-standard has-post-thumbnail hentry category-charlotte-mason category-featured category-planning tag-charlotte-mason-method tag-living-books tag-narration tag-short-lessons series-making-the-transition-to-cm">
2.7.1:
<section id="primary" class="site-content">
<div id="content" role="main">
<header class="page-header">
<h1 class="page-title">Series: <span>Making the Transition to CM</span></h1> <div class="archive-description"><p>Practical ideas and tips to help you make the transition to the Charlotte Mason Method in your home school.</p>
</div>
</header><!-- .page-header -->
<div id="pps-taxonomy-series-overview">
<div class="pps-layout-default pps-columns-1">
<article class="pps-taxonomy-series__post">
I would be happy to share the full HTML privately if you would find it helpful.
