Mura's Default Document Structure as an Outline
Viewing the markup structure as an outline, it would follow the following structure:
<div class="brand">Site Name</div> <h1 class="pageTitle">$.content('title')</h1> <h2>1st Subhead (Headline in WYSIWYG)</h2> <h3>2nd Subhead (1st Subhead in WYSIWYG)</h3> <h4>3rd Subhead (2nd Subhead in WYSIWYG)</h4> <h5>4th Subhead (3rd Subhead in WYSIWYG)</h5> <h6>5th Subhead (4th Subhead in WYSIWYG)</h6>
Note: It is by design that the headings in the WYSIWYG editor do not match the output. This was done to help maintain a logical document structure by allowing non-technical content-contributors to focus just on the content they are working with within the editor, rather than entire html document.
