HTML is a much simpler language.
HTML is very easy to learn, especially for someone familiar with the Web. In addition, the Web is overflowing with resources to help with the learning as well as great references. The World Wide Web Consortium (W3C) offers a good HTML introduction as well as many more lessons. TechRepublic provides numerous downloads about HTML, including an HTML reference guide and a CSS Reference Table.
You can find reference material from SitePoint with sites devoted to HTML and CSS.
There are tons of books available about HTML. Ian Lloyd's recently released The Ultimate HTML Reference, is a great resource in a surprisingly hard bound book. It provides a thorough discussion of each HTML element, along with example code and browser compatibility information.
Another good offering is HTML Dog: The Best-Practice Guide to XHTML and CSS.

About Munin - http://munin.projects.linpro.no/
Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort.
Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity-wise on any resources.
Munin uses the excellent RRDTool (written by Tobi Oetiker) and the framework is written in Perl, while plugins may be written in any language. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for data. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).
