Thought I'd pass along the CSS I've hacked together for my site. A few pieces here and there from others and a bit of my own. Thanks to Basileus and Langy for their code and whatnot.
The purpose of this is to set OP up as a "white page on background" look instead of the floating text look. Some may like it, some won't. This is pretty simple overall, and may have oddities I've not encountered. Comments and suggestions are more than welcome, just sharing what I've fumbled through (I am no CSS master by any means). :)
See it on my campaign: https://exalted-duty-and-honor.obsidianportal.com
Code
/* SETS MAIN PAGE LAYOUT */
.main-content-container {font-size:14px !important;}
.campaign-public-layout #content {background-color: #F7F7F7;}
/* SIDEBAR TWEAKS */
.campaign-public-layout #sidebar .module {margin-bottom: 0px; background-color: #D1D1D1; border-style:solid; border-width:1px; border-color:#D1D1D1;}
.campaign-stream-module .summary {font-size: .8em;}
.sidebar-quick-stats {display:none;}
.sidebar-last-updated {background-color:#D1D1D1;}
/* REMOVES SPACE ABOVE BANNER */
.campaign-public-layout #campaign-summary-row .row {opacity: 0.0; height: 30px}
