What is Good Css

After eight years of designing in the browser, this is a short list of things I believe to be true.

What good CSS does

  • Doesn't break any functionality of plain html.
  • Makes an interface more readable for everyone on any device.
  • Enhances the usability of an interface for all devices.
  • Allows you to quickly change a single interface without breaking other unseen interfaces.
  • Renders quickly in the browser.
  • Is 60fps (no jank on window resize or during scrolling).

What good CSS is

  • Highly reusable - even across projects.
  • Well documented.
  • Easy to read and understand.
  • ID free.
  • Mobile-first.
  • Easy to maintain.
  • Very very small.
  • Unassuming.
