> I use the Stylus extension for Chrome (also available on Firefox) to write user styles for sites, mostly to improve the legibility of text, but for sites like HN and Reddit that I browse a lot I've customised their look and feel extensively to match my tastes. Creating a custom style for a site just requires you to click the Stylus button in the toolbar, click on the site name at the bottom of the menu to create a new style and open the editor in a new tab and then add your CSS and hit save.

Yes, I'm talking about that kind of thing. It's trivial for people who want narrow sites to put a max-width on the root element that way. As someone who wants wide sites, how do I do undo all these designers' narrow widths without having to figure out manually what each individual site has done?
