The only codes I know of that you'll need are the following:
Code:
<title>:BROWSERTITLE:</title>
<link rel="stylesheet" href="templates/themename/stylesheet/link.css" type="text/css" />
:ARTICLETITLE: - for page titles
:ARTICLECONTENT: - for page content
:ARTICLEDATE: - if you want to display dates
:LINKSBAR: - horizontal link menu (holds admin links in admin panel)
:SIDEFEED: - vertical/semantic link menu
Everything else is really up to customization. If you look at my site (
Familiar Elements) you can see a bit of what I've done for themes.
Otherwise it's just regular coding.
