SenCSs stands for Sensible Standards CSS Framework, (pronounced "sense"). It supplies sensible styling for all repetitive parts of your CSS, and doesn't force a lay-out system on you. This allows you to focus on actually developing your website's style.

What SenCSs is and is not

For one, SenCSs isn't a framework like other CSS frameworks. It doesn't include a layout system, and I'm actually not sure it should be called a "framework" – But I'll go with it until I find a better term.

Now, if not a layout system littered with silly classes and pre-set grids, what does SenCSs do for you? SenCSs does everything else: baseline, fonts, paddings, margins, tables, lists, headers, blockquotes, forms and more. All the stuff that's almost the same in every project, but that you keep writing again and again and again. SenCSs handles that for you. And nothing more.

What does SenCSs do for you?

  • Stays close to the browsers base styling, but adding some sense to it
  • Sets a vertical rhythm for all elements (18px baseline)
  • Sets a common typographic standard across browsers
  • Has fonts specified for windows, mac and linux
  • Is optimised, meaning no double resets, to make the CSS as efficient as possible

What does SenCSs not do?

  • Force a lay-out system on you
  • Sneak in unsemantic classes
