Just write HTML and make it look good

Introducing sem.css, a minimalist class-less stylesheet that makes your pages look good only by writing HTML.

This simple stylesheet was born from three things:

• How the rendering of HTML without CSS hasn't changed much since the first Web browser in 1991.
• How common readers in some browsers (like the one in Safari) simplifies the styling the pages to focus on legibility.
• How writing CSS for simple pages is painful or at least time-consuming.

Much of this stylesheet was inspired from new.css, with a few changes to vertical rhythm and markup for button links, and no external fonts.

NPM
