So, I decided to create some simple starter templates to help people out who have little to no CSS ... but would like to change the default look of their Obsidian Portal site. By no means do I only plan to do three (and hopefully I'm not alone) but I think this is a good start. The Obsidian Portal community has always been good to me, and this is my way of paying back/paying forward.
I tried to make these "simple" ones as "plug and play" as possible. No wonky fonts or images or anything like that. They should function as a great starting point for much more complicated stuff.
* "Black & Red":http://www.obsidianportal.com/campaigns/free-template-simple-black-red
* "Black & Green":http://www.obsidianportal.com/campaigns/free-template-simple-black-green
* "Black & Blue":http://www.obsidianportal.com/campaigns/free-template-simple-black-blue
Basic Theme Series
These have some images and possibly use Google Fonts, they're still "simple" in that there's no complex CSS going on and it's still basically just a skin over the default Obsidian Portal layout. Images are selected from royalty free stock/sites.
* "The Innkeeper's Ledger":http://www.obsidianportal.com/campaigns/free-template-innkeeper-s-ledger (generic and suitable for fantasy)
* "iMetallic":http://www.obsidianportal.com/campaigns/free-template-imetallic (suitable for generic modern day/sci-fi)
