This stylesheet now really does three things: removes ad space, removes 'clutter' (i.e. too many, not-really-necessary elements in too little space), and employs some _minor_ style twists for a more pleasing look. The various parts of the stylesheet are clearly labeled. If you don't like some part, simply delete the appropriate section. Note: Some subsections of the site ('world', 'debate', 'members', ?) still use an old stylesheet - I haven't tried to style those. The articles under those headings conform to the new stylesheet (and thus to this mod). This stylesheet blocks the site's self-promoting popups. 'Blocks' here means doesn't show. Consider using Greasemonkey to modify the popup scripts or Stylish-creator Jason Barnabe's YesScript to block the site from using javascript altogether. Tip: The 5/week article limit imposed on non-registered non-subscribers is cookie-based, not ip-based. Flush/block their cookies and continue reading.
Based on Economist.com - remove clutter (http://userstyles.org/styles/1320) Larger text. Horizontal menu with print, share, etc.
Hides elements of the Economist article webpage that I find distracting.
Remove floating OpinionLab "+" sign on the right hand side of the page. It makes the page too wide and browser shows an irritating horizontal scroll bar.
Another DarkText contrast adjustment. Black text and a smidge of color.
Trending Topics is a very CPU-intensive Flash animation which is part of the blogs pages of The Economist. It drains laptop batteries and can even prevent scrolling of the page.
Just a simple grey background that is not so tiring on the eye.
