the actual paper content format should be separated from its rendering.
i.e. it should contain abstract, sections, equations, figures, citations etc. but it shouldn't have font sizes, layout etc.
the viewer platforms then should be able to style the content differently.
<div class="abstract-container">
<div class="abstract">
<pre><code> abstract text ... </code></pre>
</div>
<div class="author-list">
<ol>
<li>author one</li>
<li>author two</li>
<ol>
</div>
should be just:
[abstract]
abstract text
[authors]
author one | email | affiliation
author two | email | affiliation
