A Clean and Comfort Stylesheet

This article serves as a complete demonstration for my org.css, a simple and clean stylesheet for org-exported HTML file. You may switch between the default style provided by Emacs Org mode, i.e., styles specified in the variable org-html-style-default and my customized stylesheet using the button at the top left corner.

Org mode is for keeping notes, maintaining TODO lists, planning projects, and authoring documents with a fast and effective plain-text system cite:dominik2003-org.

We use Lorem ipsum text to demonstrate all elements you would expect to see in the org-exported HTML pages. Note however that the .title, .subtitle and #postamble element are not included in this section.

Known Issues

The citation exporter, ox-bibtex, does NOT work seamlessly. As of Org-mode 8.3.2, I have the following issues.

Dangling Element   solved

The lisp function insert-file-contents used in ox-bibtex does not move point and insertion-marker to the end of inserted text (I’m not sure it is a bug or an intention). The result is that the citation is a dangling table not included in the bibliography div.

The expected result is 

<div id="bibliography">
  <h2>Bibliography</h2>
  <table>
  <!-- Citation content goes here -->
  </table>
</div>

But we got 

<div id="bibliography">
  <h2>Bibliography</h2>
</div>
<table>
<!-- Citation content goes here -->
</table>

Unless a patch is submitted, we may need to manually adjust this weird result.
