Neocities default styling as a classless CSS stylesheet.
<!-- In an HTML <link> tag -->
<link rel="stylesheet" href="http://ncss.lime360.serv00.net/n.min.css">
<!-- In a stylesheet -->
<style>
@import url("http://ncss.lime360.serv00.net/n.min.css");
</style>You can also place n.css in your site!
These is a SASS version at n.scss, it's basically the same thing as the original CSS, but with additional variables to customize your stylesheet.
Simply install SASS and run npm run build to generate minified CSS in the dist/ folder.
The build server is a single PHP file that requires and external source for the regular CSS (you can use any filehost you want, but I personally prefer hosting it on GitHub or any other Git hosting service) and the minified one in the root directory.
You must also upload either .htaccess for Apache or nginx.conf for nginx to the root, or else the server won't work properly.
