<h4>EN:</h4>
A simple wordpress plugin to parse shortcodes and produce a nice html/css only timeline.
This plugin provides 4 shortcodes:
<ul>
<li>[ctimeline] – a wrapper for the entire timeline</li>
<li>[ctentry] – a date label with an entry and option content</li>
<li>[ctspace] – a simple spacer</li>
<li>[ctdate] – not implemented yet.</li>
</ul>
Take a look at the screenshots to see what rendering looks like. CSS3 
transitions and html supply minimal animations. Most markup can be used within 
the shortcodes to achieve formatting and, for instance, embed images. The 
following example demonstrates,
<ul>
<li>‘fake’ super/sub sections, not using the ‘date’ param of ctentry </li>
<li>embed a picture</li>
<li>format a label</li>
</ul>
