So, what I have might be a mish-mash of Velum and my own attempt to simplify it?
Here's the original HTML of the file I was trying to simplify.
Code:
<div class="heading heading-container-single heading-size-full heading-format-full heading-alignment-flexible heading-without-image">
<div class="heading-contents">
<div class="title-subtitle-block title-block-with-element-number">
<div class="element-number-block">
<div class="element-number case-upper">1</div>
</div>
<div class="title-block">
<h1 class="element-title case-upper">STRANGE BUSINESS</h1>
</div>
</div>
</div>
</div>
And honestly, the heading block wasn't even that bad compared to some of the internal structures for particular bits of formatted text which aren't translating to Kindle very well at all.
